HKS Super SQV4 Blow Off Valve

The HKS Super Sequential Blow-Off Valve is one of the most effective blow-off valves in the market with a design that is more than 20 years old. More importantly, the SSQ delivers one of the most recognizable and unique aftermarket blow-off valve sounds that generate a high-pitched whistle between shifts.

The SQV4 is an evolution and improvement of the classic SSQ blow-off valve that features a new differential control system that provides stable operating ranges throughout all boost pressures. This blow-off valve will come with the factory-like flange, as well as all of the required accessories to make this blow-off valve ready for the installation.
