Toyota Supra performance parts - HKS SSQV blow-off valve

The Super Sequential blow-off valve is a pull-type relief valve, unlike other blow-off valves, which are push type. The SSBV is actuated by pressure alterations only, ensuring quick valve response and complete closure during idle. Standard blow-off valves must utilize large valves in order to accommodate high boost applications (high horsepower). However, these large valves react slowly and require high activation pressure to open. Smaller, fast reacting valves do not permit the air flow required for high horsepower. The Super Sequential blow-off valve 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 SSBV is made of billet aluminum and emits a unique, aggressive sound. Absolutely the best sounding blow-off valve on the market!
