Untitled document 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 aluminium and brass * Computer machined so there is no boost leak * Out-flows factory valves for improved throttle response * Direct replacement for WRX & STi factory bypass valve (MY2002+)
