The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for selected Subaru Impreza, Forester, and Legacy models equipped with the turbocharged EJ20 engine. Its advanced sequential dual-valve system, combined with the proven pull-type valve design, provides rapid and controlled boost pressure release across a wide range of boost conditions. The design helps keep the valve securely sealed under boost, reducing compressor surge and minimising stress on the turbocharger.

The valve features a robust silver-finished die-cast aluminium body that offers excellent heat resistance, outstanding durability, and long-lasting performance. When venting to atmosphere, it produces the signature HKS blow-off valve sound, highly regarded by performance enthusiasts worldwide. Designed for stable operation across both low and high boost levels, the SQV IV is equally well suited to lightly modified vehicles and more advanced turbocharged builds.

This vehicle-specific kit is engineered for compatible HKS applications and includes the necessary hardware for direct bolt-on installation. Designed for properly matched forced-induction systems where airflow, fuelling, cooling, and engine management work together, the HKS Super SQV IV is an excellent upgrade 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.
