Product Details

HKS SSQV BOV Aluminum Piping Kit increases efficiency and performance. The use of aluminum pipping offers increased durability, consistent higher boost pressure, improved response and an attractive appearance. The HKS SSQV Flange is welded on to this pipe and serves as a complete bolt on with HKS SSQV BOV.  Kit comes with everything you need for easy installation.

HKS Super Sequential Blow-Off Valve (SSQV) is a dual stage pull-type relief valve. Unlike typical push type blow-off valves, the SSQV will not leak under any level of boost because the boost pressure keeps the valve closed against its seat. This BOV incorporates both a small primary valve for ultra quick activation along with a larger secondary valve for additional discharge capacity.

The SSQV is designed to initially open the small primary valve at light throttle and load conditions, and then sequentially opens the secondary valve for additional relief capacity under high boost and load conditions. The SSQV is constructed of polished billet aluminum, which ensures long-term durability and visual appeal. This BOV produces a powerful and unique aggressive sound.

Includes BOV & hotpipe and all hardware necessary for complete installation!
