The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Nissan Skyline R33, Skyline R34, and Stagea WGNC34 equipped with the turbocharged RB25DET engine. Its advanced sequential dual-valve system provides rapid and controlled boost pressure release across a wide range of boost conditions, helping reduce compressor surge and minimise stress on the turbocharger when the throttle closes.

The proven pull-type valve design uses boost pressure to keep the valve securely sealed under load, while HKS differential pressure control ensures stable performance from low-boost street driving to high-boost performance applications. This intelligent valve design delivers rapid response and reliable operation without compromising sealing performance or durability. At the same time, it produces the signature HKS blow-off valve sound that has made the Super SQV range a favourite among performance enthusiasts.

Designed for both standard vehicles and modified turbocharged builds, the HKS Super SQV IV offers direct bolt-on installation and OEM-style fitment for compatible applications. It is an excellent upgrade for drivers seeking improved performance, quicker boost response, and a sporty sound profile for street and track use.

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.
