TurboXS Racing Hybrid 50/50 BOV Kit WRX 2002-2007 / STI 2004-2021

If you really crave it loud, then hook up with TurboXS WRX/STi blow-off valves. Like all TurboXS valves, these WRX/STi blow-off valves relieve the compressor pressure surge caused by changing gears or backing off throttle and have been used on turbocharged engines running up to 35 psi boost. Don't worry if you choose to go above 35 (if you are ever so brave)--these valves are specifically designed for use in both race and street applications.

The new Hybrid Valve gives your WRX or STi the subtlety of a recirculating Bypass Valve, combined with the power and sound of a Blowoff Valve. We recommend upgrading the factory valve when running boost above stock levels.

• Built to last from solid aluminum and brass
• Computer machined so there is no boost leak
• Out-flows factory valves for improved throttle response
• Direct replacement for 02-07 WRX & 04-21 STi factory bypass valve
