Significant effort went into developing this comprehensive performance-improving intake solution for the Supercharged 3.0 TFSI engine found in the B8 and B8.5 generation of S4 and S5. Subsequently, the X34 Carbon Fiber Intake, Audi B8/8.5 S4/S5 3.0 TFSI offers discerning enthusiasts measurable increases in horsepower and torque, more aggressive induction sound and supercharger whine, and a beautiful carbon fiber heat shield to prevent hot air from the engine bay from entering the intake.
Throughout the development process, multiple designs were modeled, prototyped, and tested - all to ensure that the X34 Carbon Fiber Intake delivers measurable performance benefits and superb fitment. The result is an optimized open-airbox design that utilizes the factory fresh air duct inlet to channel cool outside air to the filter. This large airbox design allows for a massive 4" inlet conical air filter, free of restrictive shrouding, and channels air through a CFD-optimized 4-ply silicone inlet hose that smoothly increases air velocity to the throttle body.
