02-07 Subaru WRX & STI Greddy RS Blow Off Valve

The Greddy Type RS BOV kit for the 02-07 WRX & STI is a direct bolt on, nothing else is needed to install. It gives you the option to recirculate the system with a recirculation pipe similar to stock, or you can vent to the atmosphere if you like the loud blow off valve noise. Turbo lag is the enemy of any turbocharged vehicle. Greddy's RS blow off Valve for the 02-07 WRX & STI is easily adjustable to prevent both premature boost leakage and compressor surge. Each is made of durable cast and billet aluminum frame, and the valve to diaphragm ratio provides performance that cheap piston types can not offer. The spring stiffness adjustment screw and the two different sizes give you options to accommodate to your specific turbo setup.


  • Note:
  • The Greddy RS BOV can be set up to recirculate, or vent to the atmosphere. The 06-07 STI will not be able to utilize the recirculation tube because the TMIC is larger then previous models.
  • FITMENT:
  • Subaru STI 2004-2007
  • Subaru WRX 2002-2007
