This is a compact blow off valve designed with dual ports to vent to the atmosphere, as well as into the intake. The dual ports have been designed with sequential timing which allows for a quieter operation during normal driving conditions while also having the benefits of a vent-to-atmosphere under full boost conditions. However, the Smart Port Dual Port Blow Off Valve will come supplied with an optional blanking plug to make this blow off valve fully atmospheric. 

This blow off valve offers better performance, structural integrity, and adjustability under boost when compared to the factory blow off valve. This is a direct replacement for your factory blow off valve and will come with vacuum line to make it ready for installation.

This particular blow off valve will come in a red finish to provide a clean look to your engine bay.
