HKS Super SQV4 Blow Off Valve - Subaru WRX/Legacy

The HKS developed a unique 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 a high boost and may not reach the desired boost setting. If the spring load setting is too strong, it may not open at a low boost. The SSQV will operate under any boost pressure setting without leaking from stock to highly tuned. 100% genuine HKS product. Made by HKS Co., Ltd. Japan.
