The HKS Super SQV IV Blow Off Valve is a dual stage pull-type relief valve, which will not leak under any level of boost. This ensures a quick valve response and complete closure during idle. Other push-type blow off valves require spring load settings for each vehicle specification. If the spring load is too soft, it may leak under high boost and may not reach the desired 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 from stock to highly tuned. 100% genuine HKS product. Part# 71008-AN026. Made by HKS Co., Ltd. Japan.
Fits 8/1989-12/1994 Nissan Skyline GT-R BNR32 RB26DETT
