HKS SSQV blow off

Removed from an 180sx S13 SR20det

Used Blow Off Valve (Dump Valve in the UK). Steel flange designed for the S13 Silvia 180SX / 200SX with the SR20DET & CA18DET engine. Pipe diameter is 50mm. Mount may be modified to suit a different application. Valve is in good working order.

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..
