Perrin [15-21 WRX] Recirculation Blow Off Valve - Red

Add horsepower, quicker response, and reliability with the PERRIN Blow Off Valve - a must-have replacement for the leaky, slow-responding, plastic OEM blow off valve. The PERRIN BOV seals properly where the OEM valve leaks below 3 psi of boost, and is fully adjustable for faster response times, consistent boost, and overall better drivability. It is vital that a blow off valve for your WRX recirculates the air back to the intake tract to maintain proper air-fuel ratio and driveability between shifts.
