Probably the best blow off valve on the market. This is what HKS says about this valve "The Super Sequential BOV is a pull type relief valve, unlike other BOV's which are push spring type & are prone to leaking. The SSBOV is actuated by pressure alterations only, ensuring quick valve response & complete closure during idle. Standard BOV's must utilize large valves in order to accommodate high boost/power application. However, these large valves react slowly & require high activation pressure to open. Smaller, fast reacting valves, do not permit the air flow required for high horsepower. The SSBOV incorporates both for maximum performance. It is engineered utilizing a small primary valve for ultra quick activation along with a secondary valve for additional relief capacity. The SSBOV is made of billet aluminum & emits a unique, aggressive sound." Bottom line is it makes a really cool sound and looks great.
