The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Mazda 3 MPS BL3FW (Mazdaspeed Axela) equipped with the turbocharged L3-VDT 2.3-litre MZR DISI engine. Its advanced sequential dual-valve system, combined with HKS differential pressure control, delivers rapid and controlled boost pressure release across a wide range of boost conditions. 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 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 distinctive triple-fin insert produces the signature high-frequency HKS blow-off valve sound, giving the vehicle a sporty, motorsport-inspired character. Engineered for reliable operation, it is suitable for both standard vehicles and modified turbocharged builds while delivering rapid response under varying boost conditions.

Developed specifically for compatible Mazda 3 MPS BL applications, the HKS Super SQV IV offers direct bolt-on installation and OEM-style fitment. 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.

HKS is behind some of the coolest builds and professional drivers in the world, so when you choose HKS, you choose the best.
