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 the life of the vehicle.

The Kompact Range is a direct swap for your factory valve and benefits from immediate performance and throttle response improvements, while offering unmatched reliability over the life of standard, mildly tuned or heavily upgraded engines.

Turbosmart’s Boost-Balance system means the more boost you feed these valves, the better they seal – simple as that! The Billet Manufaacturing system ensures reliability and unmatched response is achieved by our 28mm positive-sealing piston based actuation.

The Kompact BMW Kit is a performance bolt-on replacement for the factory plastic bypass valves offering a more incredible boost response and no leaks including 2 valves and silicon hoses for remote mounting.
