The HKS SSQV4 blow-off valve kit for 2008–2014 Subaru Impreza WRX applications provides a complete replacement solution with an included return kit. The kit is specified for that model range and supplies the characteristic bypass and atmospheric venting control SSQV valves are known for. It’s presented as a vehicle-specific upgrade component for turbocharged Impreza WRX models and installs in place of the factory valve.
