PERRIN Recirculation Blow Off Valve - 2015-2021 WRX (Red)

PERRIN Recirculation Blow Off Valve — 2015–2021 Subaru WRX

The OEM blow off valve is plastic, slow to respond, and doesn't seal until ~3 psi of boost — costing you horsepower and turbo response on every shift. The PERRIN BOV seals properly from the start, vents faster, and is fully adjustable to dial in exactly how you want it to perform.

Why Upgrade

• OEM BOV doesn't seal until ~3 psi — PERRIN seals immediately, eliminating boost loss
• Larger inlet and outlet eliminates compressor surge on higher boost builds
• Fully adjustable — pre-set out of the box, no tuning required
• Recirculates air back to the intake track to maintain proper AFR and driveability
• Direct bolt-on replacement — no modification required
