The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Toyota MR2 SW20 Turbo equipped with the turbocharged 3S-GTE 2.0-litre engine. Its advanced sequential dual-valve system delivers rapid and controlled boost pressure release when the throttle closes, while the proven pull-type valve design uses boost pressure to keep the valve securely sealed under load. This helps reduce compressor surge and minimise stress on the turbocharger while maintaining excellent engine response.

The valve features a silver-finished die-cast aluminium body paired with a durable metal secondary valve, providing excellent heat resistance, outstanding durability, and long-lasting reliability. The primary valve manages the initial pressure release, while the secondary valve opens as airflow demand increases, ensuring smooth and efficient operation across a wide range of boost conditions. The included triple-fin insert produces the signature high-frequency HKS blow-off valve sound that has made the Super SQV range a favourite among performance enthusiasts.

Designed for compatible MR2 SW20 applications, the HKS Super SQV IV offers direct bolt-on installation and OEM-style fitment. Optional replacement sound inserts are available for selected applications, allowing enthusiasts to customise the valve's sound characteristics. It is an excellent upgrade for drivers seeking improved performance, quicker boost response, and a motorsport-inspired 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. 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.
