The 034Motorsport 4” Turbo Inlet Pipe for the 2.5 TFSI EVO in the Audi 8S TTRS & 8V.5 RS3 is an essential upgrade to optimize power by eliminating a critical flow restriction in the intake tract. The 4” Turbo Inlet Pipe is precision cast from A356 Aluminum and utilizes CNC-Machined 6061-T6 Aluminum Turbo Inlet Adapters that perfectly mate to allow smooth air entry into the compressor housing. This Turbo Inlet Pipe retains provisions for the factory PCV system fitting in the factory location.
The optimized volume through the elbow bend and smooth transition into the compressor housing translates into substantially higher airflow than the OEM turbo inlet as well as other competitors on the market. Airflow improvements can lead to higher horsepower and torque gains in applications that require higher airflow.
