The HKS Super SQV IV Black Edition is a premium recirculating blow-off valve developed for selected Subaru WRX STI (2007-2020) models equipped with compatible EJ20 turbocharged engines. The Black Edition combines HKS's renowned Super SQV technology with a discreet all-black finish and a recirculating configuration that routes discharged charge air back into the intake system.

The advanced sequential dual-valve system, combined with HKS's pull-type relief design, is engineered to provide rapid, stable, and controlled boost pressure release across a wide range of boost conditions. When the throttle closes, excess pressure is released from the charge-air system, helping to reduce compressor surge and minimise stress on the turbocharger. The pull-type design also uses boost pressure to help keep the valve securely sealed during acceleration.

The recirculating configuration routes discharged air back into the intake system instead of venting it directly to the atmosphere. This provides more OEM-style operation and a more discreet sound level while retaining the rapid response of the HKS Super SQV IV.

The Black Edition is distinguished by its exclusive surface treatment. The valve body and upper section feature a semi-gloss black finish, while the funnel is finished in textured wrinkle black. The result is a clean, premium, and motorsport-inspired appearance suitable for both standard vehicles and modified performance builds.

The kit features a vehicle-specific design for compatible WRX STI applications. It is an excellent choice for enthusiasts looking to combine the proven performance of the HKS Super SQV IV with recirculating operation and the exclusive styling of the Black Edition.

In October 1973, two talented and young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not, or would not, produce. HKS pioneered the Japanese aftermarket industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back ECUs and sophisticated fuel management tools. HKS was clearly driving performance trends for Japanese vehicles forward!

Today, HKS is one of the world's most well-known brands and the obvious choice for you who builds a JDM car. In the assortment you will find everything from chassis products to exhaust systems and turbo kits. HKS is behind some of the coolest builds and professional drivers in the world, so when you choose HKS, you choose the best.
