Introducing the latest and greatest blow off valve for your Subaru WRX 2008-2014. Since imitation is the highest form of flattery, HKS has once again redesigned the physical aspects of the WRX Super Sequential Blow Off Valve to thwart off the counterfeiters (we all know what those crappy knock off blow off valves look like). Your Suby is pure class, which is exactly why you want the absolute best for your Impreza WRX.
Reliable functionality of the Super SQV 4 is unchanged and utilizes the same mounting flanges as all previous generation SSQVs. This assures compatibility with all optional HKS SSQV inserts, recirculation fittings and recirculation kits.
The HKS Super SQV 4 (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 SSQV4 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 SSQV4 2008-2014 WRX specific blow-off valve kit includes the hardware to vent the HKS SSQV as needed with no extra hardware or fittings to purchase.
