HKS Super SQV4 Universal Blow Off Valve

The HKS Super SQV4 Universal Blow Off Valve is the go-to turbo blow off valve for enthusiasts who want proven reliability, rapid boost relief and premium build quality. Since 1994, HKS has led the way with its unique pull-type sequential valve structure and differential pressure control system. This advanced design delivers stable operation from low boost to high boost and helps protect turbochargers by providing consistent, controlled pressure relief under hard acceleration and fast gear changes.

The latest Super Sequential Blow Off Valve 4 keeps the trusted HKS functionality that tuners demand, while its physical design has been refreshed to maintain HKS standards in a market full of imitations. It retains the same mounting flanges as previous HKS SSQV models, so it is compatible with HKS SSQV inserts, HKS recirculation fittings and HKS recirculation kits.

Why choose the HKS SSQV4 dump valve for your turbo car

  • HKS Super Sequential Blow Off Valve technology for reliable turbo pressure relief
