Why fit an aftermarket diverter or by-pass valve? Quite simply, the original equipment valves almost never hold boost when they become old or are subjected to higher boost levels than standard. High quality performance valves respond instantly to reduce between gear change lag. Resulting in better acceleration, throttle response and driveability.

We have diverter valves to fit Audi, Volkswagen, Porsche and Volvo.
