The HKS SSQV recirculation kit for 2008 Subaru Impreza WRX STi adapts the SSQV blow-off valve to a recirculating layout for that specific application. It provides the parts needed to route bypassed boost back into the intake tract rather than venting to atmosphere, helping maintain intake conditions and turbocharger behavior appropriate for the 2008 WRX STi using the SSQV valve.
