Perrin Recirculating Blow off Valve Black 2002-2007 WRX / 2004-2021 STI / 2006-2008 Forester XT

Maximize performance without sacrificing drivability with the Perrin Recirculating Blow Off Valve. Engineered for precision and reliability, this high-performance BOV is the ideal upgrade for turbocharged Subaru and other forced-induction platforms using a recirculated setup.

The unique design allows you to control the volume of air released when the blow-off valve vents. Adjusting the volume of air helps maintain the perfect amount of boost in your system during shifts without causing compressor surges. Venting too little can damage the turbo, and venting too much air can make the throttle less responsive. This adjustment is independent of the relief pressure allowing to dial in the valve for your specific set up.

Key Features:

• High Flow: With large 1.225" inlets and outlets, the Perrin BPV is sized perfectly to relieve any amount of boost pressure without fear of compressor surge.

• Robust Construction: Crafted from CNC-machined aluminum with an anodized finish, offering superior durability and corrosion resistance while adding a bold touch under the hood.

• Adjustable Response: Fine-tune valve response with an easy-to-adjust spring preload, accommodating stock or modified boost levels.

• Leak-Free Performance: Precision-engineered piston and seals ensure quick venting and airtight sealing to eliminate boost leaks and compressor surge.

• Direct Fit Installation: Designed for a seamless fit with OEM and Perrin intercooler setups, including all necessary hardware for a clean install.
