Perrin Recirculating Blow off Valve Black 2002-2007 WRX / 2004-2021 STI / 2006-2008 Forester XT | Adjustable Boost Control | Performance Blow Off Valve
Overview
The Perrin Recirculating Blow Off Valve (BOV) is a precision-engineered upgrade designed for turbocharged Subaru models including the 2002-2007 WRX, 2004-2021 WRX STI, and 2006-2008 Forester XT. This valve manages the release of excess boost pressure during throttle lift-off, preventing compressor surge and maintaining optimal turbo health. It is ideal for enthusiasts seeking to maximize performance without compromising drivability or throttle response in their forced-induction Subaru platforms.
Built with a focus on durability and tunability, the Perrin BOV features a CNC-machined aluminum body with an anodized black finish for corrosion resistance and a clean under-hood appearance. Its unique design allows independent adjustment of air volume vented and spring preload, enabling precise control over valve response tailored to both stock and modified boost levels. This flexibility ensures the valve can be dialed in for a variety of setups, from mild street builds to aggressive tuned applications.
For Subaru owners, this recirculating blow off valve offers real-world benefits by protecting the turbocharger from damaging compressor surge while maintaining smooth throttle transitions and consistent boost pressure. The large 1.225-inch inlets and outlets provide high flow capacity, ensuring quick venting without sacrificing boost retention. This balance is critical for maintaining turbo longevity and delivering a responsive driving experience on WRX, STI, and Forester XT models.
