Fits 2015-2023 Subaru WRX (VAG/VMG) with FA20DIT engines.

The HKS Super SQV4 (Super Sequential Blow Off Valve) Black Edition Return Kit Plus is a vehicle-specific kit engineered for the FA20-powered WRX. This kit features the iconic HKS pull-type relief valve in a limited black finish, designed to prevent boost leaks even under high-pressure applications. The sequential valve structure ensures precise relief across a wide range of boost levels, improving throttle response and turbocharger longevity.

This "Return Kit Plus" version is specifically designed for street-driven applications where maintaining metered air is critical. It includes the suction return hose and necessary hardware to recirculate air back into the intake system, preventing the stalling or rich-running conditions often associated with atmospheric blow-off valves on MAF-based vehicles. The kit comes with a triple-fin design to produce the signature HKS sound while providing a complete, bolt-on solution.

  • Authentic HKS Super SQV4 Black Edition valve
  • Direct-fit mounting bracket and suction return pipe included
  • Sequential pull-type relief valve prevents leaking
  • Recirculates air to intake for stable idling and drivability
  • Manufacturer Part Number: 71008-KF015B
