The Perrin blow-off valve for Subaru turbo models is a direct-fit bypass valve made to replace the factory unit. It fits 2002–2007 WRX, 2004–2021 STI, and 2006–2008 FXT applications and is finished in red. The valve provides a replacement venting option to help manage compressor surge and recirculation in turbocharged Subaru engines while retaining factory-style mounting and vacuum connections.
