The HKS's Super Sequential Blow off Valve BOV Kit (SSQV) features a unique dual-stage pull-type relief valve. Unlike other blow-off valves that are push type, the SSQV4 BOV Kit will not leak under high boost conditions nor under vacuum at idle. Also, this new version features include a nickel-plated, die-cast metal secondary valve, which is swaged to the primary valve, a stainless steel C-Clip, and a spring to increase sealing and durability. The reliable functionality of all previous versions remains unchanged.
