Sequential Low-off Valve

Blow-off (Compressor bypass) Valves can play a vital role in any successful Turbo system. They not only improve the performance of your vehicle but they increase the longevity of the turbocharger as well. They function by relieving compressor surge (pressurized air normally forced backwards through the Turbo upon deceleration) without reducing compressor speed. Maintaining compressor speed helps to minimize Turbo lag. Repeated stress from compressor surge can damage the turbocharger and cause Turbo failure.
A MUST for turbo charged cars!
