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 02-07 WRX & 04-17 STi factory bypass valve
