Perrin Recirculating Blow off Valve Red 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 specifically for turbocharged Subaru models including the 2002-2007 WRX, 2004-2021 WRX STI, and 2006-2008 Forester XT. This high-performance valve manages the release of excess boost pressure during throttle lift-off, preventing compressor surge and maintaining smooth boost transitions. It is ideal for enthusiasts seeking to maximize turbo efficiency and drivability without compromising reliability.
Built with a focus on durability and tunability, the Perrin BOV features CNC-machined aluminum construction with an anodized red 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 sets it apart from standard blow off valves that often sacrifice either performance or drivability.
For Subaru owners, this valve ensures optimal boost management during gear changes, reducing turbo lag and preventing damage caused by compressor surge. The large 1.225-inch inlets and outlets accommodate high flow rates, supporting both daily driving and spirited performance builds. Whether you are running a stock turbo or a heavily modified setup, the Perrin Recirculating Blow Off Valve delivers consistent, leak-free operation that enhances throttle response and overall turbo system longevity.
