The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Mazda RX-7 FD3S equipped with the turbocharged 13B-REW rotary engine. Its advanced sequential dual-valve system delivers rapid and linear boost pressure release across a wide range of boost conditions while helping prevent boost leaks. The proven pull-type valve design uses boost pressure to keep the valve securely sealed under load, helping reduce compressor surge and minimise stress on the turbocharger.

The silver-coated die-cast aluminium valve body provides excellent heat resistance, outstanding durability, and long-lasting reliability, even under demanding operating conditions. The distinctive triple-fin insert produces the signature HKS blow-off valve sound, giving the vehicle a sporty, motorsport-inspired character. Engineered for high-temperature and high-load operation, the valve is suitable for both standard vehicles and modified performance builds.

Supplied as a complete kit with the necessary installation hardware, the HKS Super SQV IV offers direct bolt-on installation and OEM-style fitment for compatible applications. It is an excellent upgrade for enthusiasts seeking improved performance, quicker boost response, and the unmistakable HKS sound 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.
