Blow Off Valves

The FA24 engine in the 2022+ WRX now uses an electronically controlled factory diverter in place of the pneumatic bypass valve found on all previous turbo Subaru engines. This is controlled by the ECU, and whilst it sounds like an advancement in...

Like all valves in the DV+ family, the T9381 offers significant benefits over factory-fitted electronic diverter valves – sharper throttle response, faster boost recovery on gearshift or brief throttle lifts, improved boost holding, and unrivalled...
