Turbosmart BMW 135i/335i/535i/Z4 w/ N54 Twin Turbo 3.0L Kompact Dual Port Kit - TS-0203-1050

Kompact Range by Turbosmart is a high performance upgrade for the factory plastic diverter and bypass valves factory fitted to turbocharged cars, replacing the plastic and rubber system with a Motorsport-Proven billet aluminum valve which uses our boost-balance system for optimum performance and reliability, the life of the vehicle.

Dual Port vents both to the atmosphere & back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while getting all the benefits of a vent-to-atmosphere BOV under race conditions.
