HKS Super SQV 3 (Super Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operation range from low boost to high boost. Unlike typical push type blow-off valves, the SSQV3 can not leak under any level of boost as it is designed top keep the valve closed against its seat when under boost. The HKS SSQV3 WRX/STi specific blow-off valve kit includes the hardware to both vent or recirculate the HKS SSQV as needed with not extra hardware or fittings to purchase.

NOTE: 08-09 WRX and 08-09 STi model require a different valve than the 02-07 WRX/STi model. Please choose your correct application from the drop down menu above.

FITMENT: Subaru WRX 2002-2009; Subaru STi 2004-2009;
