Turbosmart TS-0203-1250 Kompact Plumb Back BOV for BMW B3 135i 335i 535i 740i X7 Z4

Turbosmart's Kompact range is a high-performance upgrade for the plastic factory fitted bypass and diverter valves found on turbocharged vehicles. It replaces the plastic and rubber system with a race-proven, billet aluminium valve that utilises our pressure balance system for optimum performance and reliability throughout the life of the vehicle.

The Kompact range is a direct replacement for the factory valve and offers immediate improvements in performance and throttle response as well as unrivalled reliability for the life of standard, mildly-tuned or significantly-upgraded engines.

Turbosmart’s pressure balance system means that the higher the boost pressure, the better these valves seal. It’s that simple! The billet aluminium manufacturing system guarantees unrivalled reliability and response thanks to our 28mm positive sealing piston-based actuation system.

The Kompact kit for BMW is a high-performance direct replacement for the factory plastic bypass valves, providing even more incredible boost response with no leaks. Includes 2 valves and silicone hoses for remote mounting.
