HKS Super SQV4 Blow Off Valve Kit - Honda Civic Type R (FL5) 2023-2025 - Black Edition

The Black Edition finish of the vehicle specific Super SQV IV kit for the K20C, mechanically identical to the silver version but with the body and upper section in gloss black paint and the funnel in a grainy crystal black. The valve runs a sequential dual valve arrangement under differential pressure control, with a small primary valve that opens instantly on throttle lift and a larger secondary valve that the primary then pulls open once the pressure difference across the chambers peaks. The pull type relief action seals harder as boost rises, so no spring load tuning is needed to suit a given boost target. A circulation adapter is included for a recirculating setup. Average installation time is three hours.
