The HKS Super SQV IV Black Edition is a high-performance universal blow-off valve developed for custom turbocharged applications where fast and controlled boost pressure release is essential. Its advanced sequential pull-type valve design uses boost pressure to help keep the valve securely sealed under acceleration while efficiently releasing excess charge pressure when the throttle is closed. This helps reduce compressor surge and minimise stress on the turbocharger, while delivering the unmistakable HKS blow-off valve sound.

The lightweight aluminium valve body combines excellent durability with a premium black finish, providing a discreet yet refined appearance in the engine bay. The sequential dual-valve design regulates pressure release across a wide range of boost levels, ensuring fast response and reliable operation in demanding turbocharged applications. The valve also features a replaceable discharge insert, allowing it to retain the signature HKS SQV sound when configured for atmospheric venting.

Designed for universal installations, the HKS Super SQV IV Black Edition can be adapted to a wide variety of turbocharged vehicles using vehicle-specific mounting flanges and adaptors, available separately. It is an excellent choice for street-driven vehicles, track cars, and high-performance custom builds where reliability, performance, and a clean engine bay appearance are equally important.

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.
