Turbosmart Kompact Dual Port Blow Off Valve
The Kompact Dual Port Blow-Off Valve has a small profile for those of you who want a clean look in the engine bay but with the performance needed to hold boost for those of you with moderate bolt-ons. This blow-off valve will have a 50/50 combination of venting to the atmosphere at peak boost while getting recirculated back into the intake under lower boost numbers.
The Kompact Dual Port will come designed with a stock-like flange with a new gasket and hardware to make for a simple installation.
