The HKS Super SQV IV (Silver) is a high-performance blow-off valve developed for the Subaru Legacy B4 BM9 equipped with the turbocharged EJ255 engine. Designed to work with compatible HKS intake and charge-air systems, it provides rapid and controlled boost pressure release. Its advanced sequential dual-valve system and proven pull-type valve design help reduce compressor surge and minimise stress on the turbocharger while maintaining excellent engine response.

Unlike the quiet factory recirculation valve, the Super SQV IV delivers the signature high-frequency HKS blow-off valve sound, giving the vehicle a more distinctive performance character. Its position next to the factory air cleaner housing also adds a clean, motorsport-inspired appearance to the engine bay. During HKS testing, the valve demonstrated stable operation without engine stalling, making it suitable for both standard vehicles and modified turbocharged builds.

The vehicle-specific design provides direct bolt-on installation and OEM-style fitment, allowing for straightforward installation without extensive modifications. The HKS Super SQV IV is an excellent upgrade for enthusiasts looking to combine reliable performance, a sporty sound profile, and the renowned quality of HKS in one complete package.

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!
