Blow Off Valve (BOV) Adapter for 2022+ Subaru WRX e450 5" High-Density RACE intercooler deliversThe Burger Motorsports Blow Off Valve (BOV) for the 2022+ Subaru WRX mounts between the OE bypass solenoid and the vehicle, causing the unused charge air to vent to the atmosphere giving off the desired "Pshhhh" sound.
