HKS SSQV BOV Kit for 2002-07 WRX/STi #16856

This BOV kit is perfect for those looking for a direct bolt on to the stock intercooler. This kit comes with the flange and the bov, everything needed for bolt up.The HKS Super Sequential Blow-Off Valve (SSQV) is a dual stage pull type relief valve. The SSQV can not physically leak under any level of boost because boost pressure also keeps the valve closed against its seat. The SSQV is actuated by pressure alterations only, not by the rate of pressure or vacuum in the line, which ensures a quick valve response and complete closure during idle. On typical blow-off valve designs, a large valve is utilized in order to accommodate high boost / high horsepower applications. However, these large valves tend to react slowly and require high activation pressure to open, therefore are not able to activate and prevent compressor surge at light-load conditions.On the other hand, smaller, fast reacting valves do not discharge the airflow capacity required for high horsepower applications and tend to creep open and leak as the boost pressure overpowers the spring on these push type valves.
