More About Blow Off Valves
The blow-off valve releases boost pressure when the throttle butterfly valve is closed either between shifts or whenever you're lifting off the throttle. Replace a failing BOV to prevent boost leaks or upgrade to a performance blow-off valve for better sound and higher boost pressure thresholds!
