Turbo XS 02-07 WRX RFL Blow off Valve BOV - WS02-XS-RFL

With new and improved styling, the WS02-XS-RFL remains true to its roots - it's still really loud! Like all our valves, the RFL relieves compressor pressure surge caused by changing gears or backing off the throttle and has been used on turbo charged engines running up to 35 psi boost. This blow off valve comes with everything needed to install on a 2002-2007 WRX or 2004-2017 STi.
