HKS Super SQV4 Blow Off Valve Kit with Return Kit Black Edition GRB/VAB Subaru Impreza | WRX | STI 2008-2020

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure.

This Super SQV maximizes the charge-response that repeats pressure-charging and pressurized air relief by throttle on and off and supports new generations of turbocharged vehicles - ensuring the stable actuation by adopting HKS' own sequential valve structure and pull-type relief design.

The body and upper part applied with semi-gloss black paint and the funnel painted with wrinkle black paint. Applying these colors giving off quality and a tranquil atmosphere.
