Evolution MotorSports has engineered a new performance and maintenance component for the Porsche 997 Twin Turbo. The EVOMS 997TT Boost Recirculation Valve is a direct replacement for the OEM unit and features an improved and more efficient design. Our BRV is CNC machined from aircraft grade 6061-T6 aluminum, hard anodized and utilizes military spec Viton™ O-rings. Our CAD designed BRV employs the same operating principal from our 996TT piston diverter valve which has been successfully operating for nearly 8 years. Combining our successful design principles, stringent theoretical computer and real world testing, the EVOMS 997TT BRV eliminates issues of boost leaks and diaphragm sticking and deterioration that is consistent with the OEM valve in higher than stock horsepower applications.

Features:

• Direct replacement for the OEM unit
