This set comprises a pair of our solenoid operated valves together with a custom made wiring harness, that integrates seamlessly with the OEM electronics and results in absolutely no fault codes, no check engine lights, and no detriment to the performance of the vehicle in any way.
They are engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which would effectively result in a boost leak.
