The HKS Suction Return Kit is a vehicle-specific recirculating blow-off valve adapter kit developed for the Subaru WRX STI GRF equipped with the EJ257 turbocharged engine and a compatible HKS Super SQV blow-off valve. Instead of venting excess boost pressure to the atmosphere, the kit routes the discharged charge air back into the intake system. This provides a more OEM-like operating configuration and may contribute to more consistent engine performance on vehicles equipped with a mass airflow (MAF) sensor.

The vehicle-specific return hose is designed for straightforward installation with compatible HKS Super SQV III and Racing Single Valve systems. By converting an atmospheric blow-off valve to a recirculated setup, the kit may help improve drivability, provide a smoother idle, and maintain more consistent fuel control under varying driving conditions.

The HKS Suction Return Kit is an excellent upgrade for enthusiasts who want to retain the performance benefits of an HKS Super SQV blow-off valve while achieving quieter and more discreet operation. Its application-specific design ensures OEM-style fitment and direct bolt-on installation without extensive modifications.

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!
