Carbon Fiber Visual Upgrades for Audi B7 S4

The Audi B7 S4 succeeded the B6 S4 in 2005 with minor mechanical changes and a redesigned exterior. The more contemporary styling, paired with the 4.2-liter V8 engine, made the all-wheel-drive sedan a popular choice amongst business executives and performance enthusiasts alike. While it has become dated as the B8 and B9 have respectively succeeded it, the aftermarket community continues to provide excellent products for those who still rock the B7. Brand new from ECS Tuning, we have two additions that are sure to tickle the fancy of any B7 owner: our Carbon Fiber Rear Diffuser and Carbon Fiber Lip Spoiler add a more aggressive element to the B7 S4 styling that subtly hints the decade-old autobahn cruiser still packs a punch.

The diffuser is a perfectly fitted aesthetic improvement designed to accent the existing body lines while adding a hint of sporty flair. The carbon fiber weave gives the rear of your car a transformative feeling and the stubby fins make for a more dynamic look not present on the factory rear bumper. This diffuser is an excellent choice for anyone with a B7 S4 who wants to have one more reason to look back every time they park their car.

To compliment the diffuser, our rear lip spoiler similarly accentuates and amplifies the factory contours of the trunk. Once again, a touch of carbon fiber is all it takes to provide a new theme that makes for a more race-inspired vibe than the original contours offer.

These visual upgrades are some of many still being produced for the B7 S4 that are ensured to give you a new appreciation for your Audi. Grab some carbon fiber and give your car the flair it wants with the race-inspired upgrades from ECS Tuning.

Best Visual Mods for your VW MK7 GTI

With the recent release of the VW MK7.5 Facelift model, the MK7 will soon start appearing in second-hand markets. One thing we love about the MK7 GTI is its aggressive new look yet familiar interior. Of course, being a tuning company, we always think cars can be even better. The MK7 GTI is no different: our visual upgrades give a meaner and more defined aesthetic theme to the already attractive front and rear ends of the car. Our brand new Carbon Fiber Front Lip Spoiler and our Carbon Fiber Rear Diffuser are the perfect additions to even a completely stock MK7 GTI to give it a unique and race-inspired look.

Carbon Fiber Front Lip Spoiler

For the front of the MK7 GTI, our new Carbon Fiber Front Lip Spoiler is authentic and hand-laid carbon fiber material with pre-impregnated carbon fiber cloth and epoxy resin. The UV protective clear gloss coat adds durability and a beautiful finish that makes this lip spoiler shine under the chin of your MK7 GTI. This lip spoiler bolts directly in place and follows the contours of the OEM bumper for exact fitment and head-turning looks. The accurate fitment means no cutting, shaving, or modification to your original bumper cover are necessary to install this lip, so you can be enjoying a fresh new aesthetic upgrade quickly and easily.

Carbon Fiber Rear Diffuser


Our Carbon Fiber Rear Diffuser for the MK7 GTI is similar in construction, but this piece actually replaces the factory rear valence. The impeccable fitment mimics the original piece that it is styled after, but adds the appeal of carbon fiber and diffuser channels. This piece is hand-made to replace the original valence but may require some trimming for exact fitment. However, in almost no time at all, your MK7 GTI can give you a new appreciation for the added style thanks to the front and rear carbon fiber accents.

Alzor Wheels

The final touches to give your MK7 GTI a subtle change in appearance should be wheels and suspension. We suggest a set of Alzor wheels. These excellent and durable wheels are available in a range of fitments and designs to give your MK7 GTI the look you want without breaking the bank.

ECS Street Coilovers

For suspension, our ECS Street Coilovers provide a height-adjustable coilover solution designed specifically for each individual model vehicle to meet damper and spring rate requirements while providing upgraded handling characteristics. These coilovers offer 2 inches of adjustability with fixed damping engineered to be ideal for your MK7 so you don’t have to sacrifice ride quality with your lowered GTI.

The MK7 GTI fitted with stylish Alzor wheels, a new Carbon Fiber Front Lip Spoiler and new Carbon Fiber Rear Diffuser, all lowered on ECS Street Coilovers makes for a drastic change in appearance and a sleek theme inspired by a performance look. Make your MK7 GTI the aggressive and striking neck-breaker you have wanted in an afternoon with these components from right here at ECS.

ECS Kohlefaser Luft-Technik Intake and Turbo Back Exhaust for your VW MK5 GTI

One of the best ways to add power and enjoyment to your VW MK5 GTI is to add a performance intake and exhaust. When used with software tuning, your MK5 GTI can pick up considerable horsepower and torque while also providing a satisfying increase in noise. There are quite a few options for intakes and exhaust on the market, but we think our Kohlefaser Luft-Technik Intake and 3” Valved Turbo Back Exhaust are the best options for gaining power, performance and makes driving a pleasure.

The bigger of the two jobs is the exhaust installation. Exhaust increases the rate of flow for expelled waste gas and provides a throaty sound more fitting of a performance vehicle. A major drawback of aftermarket performance exhaust is that the increased volume can sometimes be obnoxious or too conspicuous.The stainless steel construction makes our aftermarket exhaust a lightweight system compared to stock, like most aftermarket exhaust, but ours has one critical difference. Our 3” turbo-back valved system allows you to flip a switch to have power and noise or switch back to a comfort and stealth mode to quiet things down.

The ECS Swivel Tips included in this kit allows you to perfectly set the angle of your muffler tips and is available in chrome or black to suit your preferences. The attractiveness, sound, performance, and adjustability make this comprehensive kit an awesome upgrade for your MK5 GTI.

Next, no stranger to this blog is our Kohlefaser Luft-Technik Intake System. The carbon fiber intake box, attractive intake tubing, and high-flow filter adds a tasteful look to your engine bay while improving the performance. The induction noise alone is a worthy benefit, but our system does more than just sound excellent. Our countless hours of research and development resulted in a system that not only looks good, but adds an impressive 17whp and 12Ft-Lbs of torque over the stock system with a tune and our turbo-back exhaust!

We are enormously proud of our dedicated hours of engineering and designing that have allowed us to bring quite possibly the highest performing, most attractive, and cost-effective aftermarket upgrades. Our intake and exhaust give you a more enjoyable driving experience and are perfect DIY’s to knock out in a weekend. We have installation documents you can read to make sure you get the job done like a professional so you can feel confident your new upgrades will install quickly and easily. Add power and performance to your VW MK5 GTI with ECS Performance Upgrades!

Carbon Fiber Upgrades for the Audi B8.5 S4 3.0T FSI

The Audi B8.5 S4, also commonly known as the B8 S4 Facelift, is a 3.0T FSI-powered, 329hp example of Audi’s superior engineering. Its massive torque and respectable power are huge draws towards the B8.5, which makes it one of the more popular models chosen by ECS customers to modify. Many of the first modifications are oriented around more power, better brakes, aggressive wheels, and loud exhaust. We absolutely love our beefed-up B8.5 S4, but what honestly ties the whole package together are the subtle (and sometimes not so subtle) carbon fiber visual upgrades which tell passersby that your supercharged Audi is more than the standard S4. ECS offers a wide range of carbon fiber modifications, all designed and developed by our crack engineering team, that will help you tell the story of your Audi’s power and prowess without ever having to speak a word.

Front Lip

Our first addition to the B8.5 S4 adorns the front fascia with a beautifully hand-laid Carbon Fiber Front Lip Spoiler. The first place many see is the naturally aggressive countenance of the supercharged sedan, so an important area of modification is that front bumper. The addition of our exclusive in-house design provides a curious and complex enhancement to the lower portion of the bumper cover while it also follows the factory contours closely. Think of this lip like you would a perfect garnish of herbs and spices on already appetizing eggs Benedict. It just fits and makes the whole experience complete.

Grille Accents and Overlay Sets

Moving north of the spoiler, but maintaining our focus on the front end, the Carbon Fiber Grill Accents and Carbon Fiber Fog Light Grille Overlay Sets compliment the new Carbon Fiber Front Lip Spoiler and give the cheekbones a pronounced look reminiscent of Kate Moss in her prime. The angular accents protrude ever so slightly with a smooth, yet angular, grace. Sitting just below the fog lights to further the theme of carbon lateral lines are the Fog Light Grille Overlays. These simple yet noticeable shelves match perfectly with the carbon lip and cheeks in a gorgeous tremolo of parallel lines of artfully laid carbon weaves. The completed set of all three front bumper cover visual upgrades provide a unique aesthetic to which admirers’ gazes will undoubtedly gravitate.

Trunk Spoiler

With the front of the B8.5 thoroughly sprinkled with carbon fiber, we can direct our attention to the rear of the vehicle. An ever-popular modification to any performance car is a ducktail-style trunk spoiler. Our contribution to the world of aftermarket spoilers offers a unique and exclusive design tailored to perfectly match the existing trunk contours. The ECS Carbon Fiber Trunk Spoiler protrudes nearly vertically as a slim and suave extension of the trunk; just a slight stroke of ornate beauty left by the mark of a calligraphy master’s quill as it leaves the paper. The ease of installation for this tail further adds to its attractiveness as a visual upgrade, as in minutes your B8.5’s profile can enjoy a brand new look.

Antenna Cover

Before returning to aero components, we want to briefly direct your eyes to the antenna ‘shark fin’ delicately placed above the rear glass. This portion of the B8.5 is what we would call an afterthought by the original designers. The unattractive blemish doesn’t have to appear tacky, though, with our Carbon Fiber Antenna Cover you can continue the theme of carbon and furnish an intentional look and feel to the otherwise forgotten antenna.

Mirror Caps

Furthermore, the loss of true brushed stainless steel mirror caps after the B6 S4 model has been a somewhat saddening change to the Autobahn-stormer. While that may be a detriment to the factory appearance of the B8.5, our Carbon Fiber Mirror Caps replace the plastic caps with striking carbon fiber alternatives. The carbon weave may not harken back to the stainless caps from older Audi S4’s, but they certainly drive the theme of race-inspired, luxury, tasteful carbon weave home.

Side Blades

The previous carbon additions have bestowed an exotic aspect to the S4, but our efforts to truly meet aggressively angry styling with beautiful refinement require we complete the motif. Our Carbon Fiber Side Blade Extensions widen the appearance of the vehicle while giving a knife-edge feel to both flanks. These blades match perfectly with the front lip spoiler and continue the congruent lines which act like a carbon fiber shadow that extends from the underside of the Audi to the ground. This achieves the look of being nearly in contact with the ground and reminds us of the original concept artwork for the B8.5 S4.

Rear Diffuser

Finally, placed under the rear bumper cover is our Carbon Fiber Rear Diffuser. The sharp fins bulging from the overlay which channel air from under the car and split the area of pressure both function as clever design improvements and aero at high speeds. The diffuser also finishes off the carbon fiber lines surrounding the lower portion of the B8.5 on all corners, giving the car a completed look and bulkier stance.

All the Carbon Fiber

Carbon fiber is the perfect way to add visual design changes to your B8.5 without adding weight and hint tastefully at the power which may lie underneath the skin of the car. Our exquisite carbon art, which is exclusive to ECS, brings a new look to the already visually striking German performance sedan. These upgrades will surely bring a smile to the face of any enthusiast who may see them. Each piece is hand-laid to perfection to ensure your new visual upgrades match the quality of which Audi owners know and expect from their vehicle and designed right here by our fantastic Research & Development department to guarantee precision and beauty. Make sure your Audi B8.5 S4 exterior isn’t left bare as you modify the engine, brakes, and suspension. ECS Tuning exclusive carbon fiber visual upgrades are an important part of your balanced barnstormer.

Step 5

Connect the crankcase ventilation hose by

pushing it into place on the turbo inlet tube.

Step 6

Install the bolt holding the carbon fiber

turbo inlet tube to the heat shield on the

rear of the cylinder head.

Note: For Jetta GLI it may be necessary to adjust the

mounting tab on the heat shield approximately

20 degrees for proper clearance.

Step 7

Tighten the bolt using a T30 Torx bit socket

and ratchet.

Step 8

Place one of the 65mm-89mm clamps over

the end of the 3” hump coupler and push

the coupler onto the carbon fiber turbo inlet


Do not tighten the clamp at this time.

Note: Pay attention to the location/direction of the clamp

screw. All 4 clamps should be installed with the clam

screw in the same direction for ease of access as well

as uniform appearance.

Step 9

Connect the mass air flow sensor

connector to the mass air flow sensor by

pushing it on until you hear the faint “click”

with the connector locking tab engaging.

flow sensor to make sure it is installed in the correct

direction. The arrow points in the direction of air

flow (to the engine).

Step 11

Insert the secondary air pipe adapter into

the air pipe filter and tighten the clamp.

Step 12

Attach the air pipe filter and adapter to the

secondary air pipe, and secure

underneath the air box.

Note: You must choose an optimal location for the

secondary air pipe filter – the unit should be

supported such that it does not move around freely

in the engine bay, and has some access to air flow.

Our filter was secured under the airbox with a

zip-tie, proving to be an adequate location.

Step 13

Install the 2 grommets into the bottom of the

carbon fiber airbox.

Step 14

Align the carbon fiber airbox and duct, and

push down on the carbon fiber airbox

until the grommets are seated in place.

Step 15

Using a T25 Torx bit, install and tighten the

two screws that secure the carbon fiber air

box duct to the radiator core support.

the Torx bit will hold the screws in place and keep them

from falling off.

Step 16

Slide the ECS Tuning high flow air filter

element with the clamp in place onto the

carbon fiber air filter tube.

Hold the air filter and tube in place in the

carbon fiber airbox to adjust the position

of the filter. Do not tighten the clamp at this

the 3” straight coupler.

Step 21

Be sure the Air Filter Tube to Air Box seals

remain in place during installation.

Step 22

Loosely install the 15mm long Allen bolt that

secures the carbon fiber air filter tube in


Step 23

Carefully adjust the carbon fiber air filter tube,

the mass air flow sensor, and both couplers

so everything is aligned nicely and both

couplers are properly seated.

Tighten all 4 hose clamps, paying attention to

the alignment of the clamps in order to obtain

a clean and neat appearance.

Step 24

Tighten the air filter tube securing bolt and

stainless steel washer using a 4mm Allen

socket. A ratchet extension can be helpful


Step 25

Place the carbon fiber airbox lid on top of

the carbon fiber airbox.

Be sure the Air Filter Tube to Air Box seals

are still properly in place during installation.

Step 26

Remove the battery cover by pushing the

release tab in the direction of the arrow on

ECS B8 Audi A4 S-line/S4 Carbon Fiber Front Lip

ECS is proud to present a brand new piece of carbon fiber for your Audi B8 A4 S-Line/S4: our in-house designed Carbon Fiber Front Lip Spoiler! If you are looking for a way to give your front bumper a more aggressive and unique appearance, this is it.
While the front end of your B8 is already a fantastic blend of converging, angular lines, this lip adds an aggressive accent to the front facia by poking out from underneath the bumper cover.

We designed this lip to fit easily in place over your factory bumper cover where it mimics the lower section of the bumper and accentuates the original lines of the car.
We stayed true to the feel and design of the Audi’s factory front end, while minimally increasing the impression the profile leaves on viewers through the addition of familiar lines paired with the illusion of a lower and wider head-on view. 

The lip is not only simple to install, but also follows the contours of your B8’s front bumper precisely for a more satisfying and direct fit.
By fitting so precisely, you are able to enjoy the stylish improvements made by the meticulously laid carbon weave that will appear to flow beautifully from underneath the bumper cover along the topography of the lip. 

While most carbon fiber yellows and peels in sunlight, we require our carbon products to endure rigorous heat and UV testing. Since the lip spoiler is made from hand-laid carbon fiber and coated for protection against heat and UV light, you will be enjoying those aesthetic improvements to your Audi for a long time. 

This front lip spoiler is an excellent choice for someone interested in making a dramatic change to the style of their Audi during a afternoon. With a simple and enjoyable installation, you can spend more time appreciating the subtly combative look now observable on your Audi. While the benefits are purely aesthetic, they can be the final touches that set your B8 apart; either on the road, or at the car meet.

Tyler’s B8 A4 Daily Monster

Modifying cars for many enthusiasts is not only a hobby, but a form of expression you take with you everywhere. More accurately, this form of self-expression takes you everywhere. For our friend Tyler that was exactly the purpose behind this B8 A4 build.

Tyler sat down with me at a small sandwich shop in Ohio to give me a better idea of what he wanted his Audi to be. An avid enthusiast, Tyler is not new to modifying cars. Since his DC2 Integra GSR in 2001, Tyler’s car history is filled with Subaru and Honda enthusiast vehicles. All of his builds have been heavily modified. Specifically, most of his previous cars included big turbos, extensive performance modifications, were intended for dedicated ‘spirited’ driving: both on tracks, or back roads.

Alzor 349 19×9.5 square sets on 235/40/19 tires finish off Tyler’s stance with an aggressive, yet classic look.

The Audi he most recently built tells something of a different story. A few years ago, Tyler made the switch to German performance with the purchase of an Audi B7 A4. One of two automatics he has ever owned, he enjoyed the B7 for its comfort and reliability. While he is not looking for something to put earthquake-inducing power into, an important factor in his driving experience was to be able to enjoy the car every time he drove it.

His B8 is exactly that: a beefed up, mature, and comfortable daily driver. With a new Frankenturbo, new pistons and rings from Audi, aesthetic changes like the ECS Carbon Fiber Trunk Spoiler and Engine Cover, and a few bolt-ons, Tyler took his run-of-the-mill A4 and turned it into something special. This car is an extension of his personality. He is as much an outdoor enthusiast as he is a car enthusiast, as you can see by his bike and kayak racks. The Audi checks those boxes perfectly.

“The car was supposed to be something I could drive every day. That could take me kayaking, hiking, or snowboarding. Something I could rely on year-round and still enjoy”

This idea is apparent when one hops in the rear seat and looks over to see a Recaro baby seat. Tyler and his wife are expecting shortly, and have already purchased things like the seat and VW clothing to indoctrinate their new son as quickly as possible into the way of the car enthusiast. The inclusion of his new family addition is exactly what the Audi was ready for.

While His B8 makes significant power over a stock equivalent, the car remains comfortable over bumps and is never excessively loud. Even more surprising is the traditional manual transmission equipped with the Quattro rather than the now favored automatic. The signs of an enthusiast are all there, coupled with the reliability and panache of a classy every-day utility vehicle.

ECS Carbon Fiber beauty and performance pieces accent the natural beauty of the Audi under-hood, and do more for performance than just sit pretty.

Overall, Tyler is able to drive a well equipped and comfortable Audi that is still able to satisfy his enthusiast bug without making hardly any sacrifice. Isn’t that what tuning is about?

Attractive and easy to install, you can have this system in place in just a few hours or less.  Whether you have purchased the charge pipe only kit or the complete kit with our ECS Tuning intercooler, you’ll have everything you need for a trouble free installation. Thank you for looking to ECS Tuning for all your performance and repair needs.  We appreciate your business!

Step 1:

Safely raise and support the vehicle

Never get underneath a vehicle that is supported only by a jack.  Always make sure that the vehicle is securely supported on jack stands or an automotive lift.

Step 2:

Remove the LF wheel.  Here we are using a wheel hanger to support the weight of the wheel when we remove the lug bolts and use of a Protecta Socket will prevent damage to the wheel finish.

Wheel hangers are especially helpful for cars that use lug bolts and they make wheel spacer installation much easier too.  The Audi A4 requires a 14mm x 1.5 thread hanger, available on the ECS Tuning website as ES2636260.

Step 3:

Remove the lower insulation panel or skid plate, whichever you have installed.

For an in depth installation guide and fastener location chart for B8 skid plates, refer to our ECS Street Shield Skid Plates, ES2771379 or ES2771912

Step 4:

Locate the plastic guard above the LH CV shaft.  Remove the two securing nuts, then pull it forward, pivot it around the CV shaft, and remove it.

Step 5:

The LF fender liner needs to come out next, and it’s held in place by a number of different fasteners.  We’ll point them all out over the next few steps.

In this step, remove the two forward screws

(1) at the edge of the fender, then using a pick remove the two clips

(2) just to the right.

Step 6:

Remove the expanding rivet that holds the fender liner to the body.  It’s located just forward of the CV shaft.  The expanding rivet will come out in two pieces, center pin first, then the rivet body.

Step 7:

Remove the two clips on the top side of the fender liner, forward of the suspension strut.

Step 8:

Finally, remove the three rearward fasteners consisting of one nut and two clips.  Now carefully pull the fender liner out from the lip of the fender, then downward, and remove it from the car.

Step 9:

On the RH (passenger) side, remove the two forward fender liner screws at the edge of the fender.  It is not necessary to remove the fender liner or the wheel on this side.

Step 10:

On both sides, reach in behind the bumper and disconnect the fog lamps (LH shown).

Step 11:

Remove the four screws along the rear edge of the lower radiator shroud.

Step 12:

Inspect the side view of the bumper cover/fender on the right.  There is a bolt on each side that secures the bumper cover to the fender.  We have overlaid the bolt in this illustration so you can visualize its location.

Step 13:

Remove the bolt on each side that secures the bumper cover to the fender (see the illustration in step 12).  On the RH side, you can access the bolt by pulling back the edge of the fender liner.

Depending on model and production date, your vehicle may have two bolts on each side that will have to be removed prior to pulling off the bumper cover.

Step 14:

Pull out on both rear edges of the bumper cover as shown to release them from the clips on the fender.

Step 15:

Remove the four upper radiator shroud screws.

Step 16:

Lift up on the rear edge of the radiator shroud, then pull it rearwards to unhook it from the grille, and remove it.

Step 17

Look down between the grille and radiator and disconnect any components that are attached to the back side of the grille.

Depending on model, you may find the following:

  • Homelink Transmitter
  • Ambient Air Temperature Sensor

Step 18:

Remove the two screws at the top corners of the grille.

Step 19:

Remove the bumper cover by pulling it straight forward.  It’s not heavy but slightly awkward.  If you’re careful you can balance it in the middle, but it’s much easier if you have a friend help you with it.

Step 20:

With the bumper cover removed, we’re ready to start on the charge pipes.  Let’s start with the turbo outlet pipe.  Loosen the hose clamps on the original turbo outlet hose at the turbo damper on one end, and the intercooler inlet on the other.  Pull the hose off and remove it.

Step 21:

Remove the three screws on the original turbo damper, and remove it from the turbo outlet. Be careful not to lose the small o-ring seal between the two.

Step 22:

Thoroughly clean the o-ring and the seal groove, then install the o-ring into the groove on the turbo outlet, using light grease to hold it in place.

Step 23:

Install the new turbo outlet adapter using the original screws.

Step 24:

Now let’s move on to the intercooler outlet and throttle body pipes on the LH side of the vehicle.  Look down in front of the ABS pump, locate the MAP sensor (on the top end of the intercooler outlet pipe) and disconnect it.

Step 25:

Pull the power steering hose out of the clip on the top end of the intercooler outlet pipe.

Step 26:

Loosen the hose clamp on each end of the original throttle body hose.

Step 27:

Pull the throttle body hose off each end and remove it from the car.

Step 28:

Loosen both hose clamps on the original intercooler outlet hose, then pull it off both ends and remove it.

Step 29:

Pull the power steering hose out of the clip on the side of the intercooler outlet pipe.

Step 30:

Remove the three mounting nuts, then remove the original intercooler outlet pipe from the car.

Step 31:

Remove the three mounting bushings from the original intercooler outlet pipe in the following manner:

  1. Slide out the metal sleeve washer from each one
  2. Pull the rubber bushings out of the intercooler pipe bracket

Each of the three bushings is a different size and only fits in its corresponding location.

Step 32:

Install the original bushings and sleeves into the new intercooler outlet pipe bracket.

Note the different size and shape of the mounting holes in the bracket.  Make sure each of the three bushings is installed in its correct location.

Step 33:

Remove the two screws, then carefully remove the MAP sensor from the original intercooler outlet pipe.

Step 34:

Install the MAP sensor into the new intercooler outlet pipe using the new screws provided with the kit.

If you have purchased the complete kit and are installing a new ECS Tuning intercooler, skip to Page 35 to install the intercooler at this time.

If you are installing the charge pipes only, continue on the next page.

Step 35:

Loosely place a hose clamp onto each end of the correct silicone coupler for the intercooler you are using (see below), then push the coupler onto the intercooler outlet.

Stock Intercooler:

Coupler: 2.5” to 2.25” Reducing, small end located on intercooler.

Clamps: 60-68mm located on intercooler side, 67-75mm located on pipe side.

ECS Intercooler:

Coupler: 2.5” Straight.

Clamps:  67-75mm on both ends.

Step 36:

Install the new intercooler outlet pipe into place, pushing it into the coupler on the bottom and over the studs on the frame.

Step 37:

Install and tighten the three nuts on the intercooler pipe bracket.

Step 38:

Tighten both the T-bolt clamps on the silicone coupler.

You may position these clamps as desired to achieve the look you want.

Step 39:

Reconnect the MAP sensor.

Step 40:

Loosely place a 67-75mm hose clamp over each end of one of the silicone hump couplers, then push it onto the top of the intercooler outlet pipe.

Step 41:

Push the straight coupler onto one end of the new throttle body pipe, then loosely place two 67-75mm clamps over the coupler.

The throttle body pipe is the same on both ends and can be installed in either direction.

Step 42:

Install the throttle body pipe into place.

Step 43:

Make sure both silicone couplers are aligned properly, then tighten all four T-bolt clamps.

You may position these clamps as desired to achieve the look you want.

Step 44:

Now, moving back to the turbo outlet pipe, loosely place a hose clamp onto each end of the correct silicone coupler for the intercooler you are using (see below), then push the coupler onto the intercooler inlet.

Step 45:

Inspect the new turbo outlet pipe and identify the ends. The turbo end has a 60 degree bend on it while the intercooler inlet has a 123 degree bend.

Step 46:

Slide the remaining hump coupler over the “turbo” end of the turbo outlet pipe, with two 67-75mm clamps loosely installed.

Step 47:

Install the new turbo outlet pipe into place, routing it over the core support brace.

Step 48:

Push the turbo outlet pipe up into the hump coupler, then tighten the clamps. make sure that the pipe does not hit the brace.

Step 49:

Tighten the two T-bolt clamps at the intercooler.

Step 50:

Reassemble the vehicle:
Reinstall the bumper cover.
Reinstall the fender liner
Reinstall the skid plate/insulation Panel
Install and torque the LF wheel to 120 Nm (89 Ft-lbs).

ECS Tuning Carbon Fiber Intakes are clear coated for excellent finish durability and UV resistance right out of the box.

Carbon fiber can be washed with any gentle cleanser or soap.  If it is safe for the paint on your car, it will be safe for the carbon fiber.

Be extra careful not to nick or deeply scratch the clear coat on the carbon fiber.  This can lead to water intrusion into the carbon fiber which will damage the finish and the integrity of the intake.

If the clear coat does get nicked or deeply scratched to expose the carbon fiber, seal the damaged area thoroughly with a clear coat touch up or clear nail polish.

To retain UV resistance and protect the finish, we recommend regular waxing with a high quality Carnauba wax.

Small surface scratches and light oxidation can be buffed out using the same methods and cautions you would use on the vehicle paint.
