The HKS Super SQV IV Universal is a high-performance universal blow-off valve designed for custom turbocharged applications and as a replacement or upgrade for compatible older HKS SQV blow-off valves. When the throttle closes, the valve rapidly releases excess boost pressure from the intake system, helping to reduce compressor surge and minimise stress on the turbocharger. At the same time, it delivers the unmistakable HKS blow-off valve sound.

The advanced sequential pull-type valve design uses boost pressure to keep the valve securely sealed under acceleration, reducing the risk of boost leakage even at higher boost levels. When the throttle is lifted, the valve responds instantly, releasing excess pressure quickly and in a controlled manner. Its durable all-metal construction provides excellent reliability and long-lasting performance, making it suitable for everything from street-driven vehicles to high-performance builds and dedicated track cars.

The HKS Super SQV IV Universal can be installed on a wide variety of turbocharged applications using vehicle-specific or universal mounting flanges, which are available separately. This makes it a flexible solution for custom intake pipe configurations and different installation requirements. The kit includes the necessary hose fittings, O-ring, C-ring, and an air filter for installation.

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.
