The OEM BOV's tiny outlet limits the boost-venting rate and may result in leaks. The PERRIN BOV has a much larger adjustable outlet, and 1.225" inlets/outlets designed for balanced flow and boosted-system response without excessive boost loss. Adjustable spring tension in the cap tailors the valve's venting and pressure-release rate, while the unique design allows you to control the air volume. To maintain proper air-fuel ratio and driveability, the PERRIN BOV recirculates the air back into the intake track. Crafted from 6061-billet aluminum, the durable body and precise components do not require special tools or frequent maintenance. Each blow off valve comes pre-set for bolt-on convenience in WRX/STI vehicles.
