034Motorsport’s P34 Cold Air Intake System delivers improved power, sound, and acceleration to B9 Audi A4/Allroad & A5 owners in a clean OEM+ package.

Through extensive evaluation of the factory airbox design, 034Motorsport’s engineers were able to create a performance replacement that allows for increased airflow to the turbocharger and engine. The P34 Air Intake System offers measurable performance improvements, simple bolt-on installation, and unsurpassed fit and finish.

Significant effort went into developing this comprehensive performance intake solution for the longitudinal EA888 2.0T Gen 3 engine found in the latest generation Audi A4/Allroad & A5. Subsequently, the P34 Cold Air Intake System offers discerning enthusiasts measurable increases in horsepower and torque, sporty induction and turbocharger sounds, and a beautiful airbox design.

Throughout the development process, multiple designs were modeled, prototyped, and tested – all to ensure that the P34 Cold Air Intake System delivers measurable performance benefits and superb fitment. The result is a partially-enclosed airbox which uses the factory fresh air inlet duct and heat shield, while housing a massive 5″ inlet conical air filter, and a CNC-machined billet aluminum velocity stack feeding a reinforced silicone turbo inlet pipe.
