HKS Super SQV IV Sequential Blow Off Valve Kit – Universal (Black or Chrome)

Brand: HKS Japan

The fourth generation of the iconic HKS Super SQV (Sequential Blow Off Valve) combines sharp response, durable build quality, and that famous high-pitch "chirp" known around the world. Available in either a stealthy Black finish or a traditional Chrome body, the SQV IV is built for turbocharged vehicles that demand reliability and street presence.

Using a unique sequential valve structure with a pull-type relief system, the SQV IV guarantees consistent performance across all boost levels — from light throttle to full boost. Unlike push-type valves, HKS's pull-type design ensures stable operation without leaks, even under extreme pressure loads.
