Racing Bypass Valve

HKS Racing Bypass Valves function similar to Standard Bypass Valves but incorporate an additional pressurized port to aid under severe boost conditions. They can also be used as safety "pop-off" valves if the second port is connected to a pressure source.

Super Sequential Blow-off Valve (SSQV)

HKS Super Sequential Blowoff Valves (SSQV) are dual stage pull type relief valves that by design do not leak under high boost conditions or under idle vacuum and is actuated by pressure alterations to ensure a quick primary and secondary valve response. MORE INFO
