HKS Super SQV4 Blow Off Valve features a unique pull-type sequential valve structure and a differential pressure control system. This advanced system allowed for a broad operation range from low to high boost. This pull-type relief design ensures stable operation regardless of boost pressure.

The HKS Super SQV4 Blow Off Valve includes a nickel-plated, die-cast metal secondary valve, which is swaged to the primary valve, a stainless steel C-Clip and spring to increase sealing and durability. To assure buyers that they are purchasing an authentic HKS product, the new design incorporates a holographic HKS logo on the back of the valve, as well as additional HKS logos cast onto the body structure.

The Super SQV4 utilizes the same mounting flanges as all previous generation SSQV's to assure compatibility with all optional HKS SSQV inserts, recirculation fittings and recirculation kits. 71008-AT009
