Dual Valve Design, Sequential System
The HKS Super Sequential Blow-Off Valve (SSQV) is a dual stage pull-type relief valve, which will not leak under any level of boost. THis ensures a quick vlave response and complete closure during idle.
Pull-type blow off valves will work for any turbocharged vehicle, from stock to highly tuned.
Push-type blow off valves require spring load settings for each vehicle specification. If yte spring load setting is too soft, it may leak under high boost and may not reach the desried boost setting. If the spring load setting is too strong, it may not open at low boost. The SSQV will operate under any boost pressure setting without leaking.
