When you have surpassed the power levels on your factory blow off valve, then it may be time to upgrade to the Turbosmart Kompact Dual Port Blow Off Valve. This particular blow off valve vents both to the atmosphere, and back into the intake. This blow off valve features ports with sequential timing which promotes a quieter operation under normal driving conditions. However, this blow off valve still has an aggressive sound under larger boost loads. 

This blow off valve is crafted from machined billet that has a lightweight alloy piston. Compared to the factory plastic blow off valve, the Kompact Dual Port is all around a stronger, better-performing blow off valve that will release pressure quicker, allowing for faster acceleration in between shifts. 

Included are the gasket, worm clamp, as well as the shims to make for a ready installation.
