The Cusco Air Suction Pipe Kit for the Scion FR-S & Subaru BRZ is a direct factory replacement component that enhances air intake efficiency. Since naturally aspirated applications are very sensitive to modifications, certain aspects such as air intake is a critical factor in performance enhancement.
By providing a smoother internal intake wall lining than the OEM factory ribbed design, a significant increase in air intake velocity can be realized. Smooth, transitional air flow equals less turbulence. The aluminum pipe is a direct replacement of the factory piece where the air intake filter box is retained in its original position.
To make this product 100% factory replacement, the OEM "Sound Creator" pipe was still made to be compatible with the aluminum air suction pipe. The sound creator function can also be eliminated by installing an bung to the port, completely sealing off any air flow to the air intake system.
Compatible with factory ECU.
