Product Description

The HKS 71008-AH012V SUPER SQV4 Return Kit Plus is a vehicle-specific blow-off valve system engineered exclusively for the FL5-generation Honda Civic Type R. Designed around the K20C 2.0L turbocharged four-cylinder engine, the relief-less SUPER SQV4 system quickly releases excess boost pressure during throttle-off operation, helping reduce load on the turbocharger.

The system is designed to operate across the boost range while maintaining stable set boost pressure at higher boost levels. When configured for atmospheric discharge, the SUPER SQV4 produces its distinctive high-frequency operating sound. The kit also includes a suction return hose, allowing recirculated operation and making the system suitable for the intended return configuration.

The 71008-AH012V includes the SUPER SQV4 main unit, FL5-specific adapter, mounting bracket, suction return hose, and hardware. HKS specifies an average installation time of approximately three hours. This application is specifically for the FL5 Civic Type R and should not be substituted for the separate FK8-generation kit.
