This BOV offers an affordable alternative to get great performance! The blowoff valve is a requisite part in a turbo-charged engine as it relieves pressure when you take you foot off the gas to shift gears or slow down - well, the turbos don't just turn off so are still pushing a lot of air, and if that air can't go into the engine (throttle plate is closed with foot off the gas) then it will back-wash into the turbo (literally causing it to stop!) and can severly damage the turbo bearings. The BOV releases that pressure from the intake system, and this Type-FV Style BOV is an atmosphere / open loop valve, meaning it releases the air into the open atmosphere. It is adjustable for various boost levels by loosening the lock nut on top and screwing in our out the threaded shaft.
Comes as a complete kit as shown below..
NOTE: Being an open-loop BOV, you will also need a plug when installing on a 3000GT/Stealth. We offer a 1.5-inch BOV Plug separately.
