HKS Super SQV4 is a sequential pull-type blow-off valve for the Subaru WRX STI GRB / GRF chassis with the EJ257 turbo engine. This is the return-kit version, supplying the recirculation (plumb-back) tube and model-specific adapter so vented air routes back into the intake for clean idle and surge protection. The two-stage piston gives a sharp release and quick recovery.
