The 034Motorsport X34 Carbon Fiber Lower Intake Box and Fresh Air Duct for the Audi 8S TTRS and 8V.5 RS3 complements the 034Motorsport X34 Cold Air Intake (both the open top and closed top versions). This combination improves airflow and throttle response with dyno-proven horsepower gains.
034Motorsport’s engineers spent extensive effort to develop a complete cold air intake solution for the TTRS and RS3 that yields airflow and pressure drop gains over the well-designed factory airbox, which can lead to higher horsepower and torque gains in applications that require higher airflow, like upgraded turbos. During the development process, many iterations were designed, prototyped, and tested, which resulted in this beautifully-manufactured Carbon Fiber Cold Air Intake System that flows better than no intake at all (see pressure drop chart below).
Pressure Drop is the difference in ambient air pressure and the air pressure measured at the turbo inlet across the engine's rpm range. The higher the pressure drop at any given rpm, the more restrictive the intake system is, reducing airflow.
Intake Configuration | Chart Color |
Pressure Drop |
X34 Open Top CAI w/ X34 Lower Airbox and Fresh Air Duct | Green | -2.43 psi |
X34 Closed Top CAI w/ X34 Lower Airbox and Fresh Air Duct | Yellow | -2.52 psi |
No Intake (Open Turbo Inlet) | Blue | -2.50 psi |
X34 Closed Top CAI w/ Stock Lower Airbox | Gray | -2.61 psi |
Stock Intake | Red | -2.77 psi |
034Motorsport carefully selected the carbon fiber weave on the intake tube and upper airbox heat shield to match the factory carbon fiber engine trim found in the Audi TTRS & RS3 2.5 TFSI engine bay. The 034Motorsport Audi TTRS & RS3 Cold Air Intake System was designed to fit like a factory part, and mates directly to the turbo inlet pipe and factory lower airbox to provide an OEM+ look.
