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.
Full recirculating BOV. The Plumb Back system recirculates all excess pressure back into the intake system. Great for enthusiasts not wanting to be noticed but wanting the performance and reliability benefits of a quality BOV.
