HKS blow off valve protects engine and turbo system by preventing both boost leakage and compressor surge. Quick response and complete closure when idle are other characteristics of HKS blow off valve.

Blow off and bypass valves are two types of valves uses to take away excess pressure off a turbocharged engine. A blow off valve passes the pressure out into the atmosphere, while the bypass valve puts the pressure back into the air intake system.

HKS blow off valve prevent compressor surge and protects the centre cartridge of the turbo system. HKS blow off valve utilizes special pull technology to expel air from the turbo system. The smaller structure of HKS blow off valve reacts to low pressure situations while providing optimum performance under high pressures.

HKS blow off valve incorporates the best design concepts for blow off valves, to bring in a seamless

The discharge port looks stylish and produces great sound. It also perform well under all conditions – both street and off road conditions. The chances of leaking under high pressure are also plugged with its superior valve design concepts.

HKS blow off valve actually use a small primary valve that facilitates quick activation and larger secondary valve for enhanced relief capacity. The twin advantage (of faster activation and better discharge) makes HKS blow off valve a special choice for motorists. Made of billet aluminium, the equipment is stable, durable and produces the smoothest sound. Many users claim HKS blow off valve produces the best sound in the city.
