From its unique chirping sound, to the ability to out-perform OEM units, this is a blow off valve one can depend on. The latest HKS Super SQV4 Blow Off Valve employs the same design qualities as the original, which involves a pull-type sequential valve structure with a differential pressure control system. This design allows for stable operating ranges from low, to high boost pressures.
Additionally, this particular SQV4 will come with an OEM-like mounting flange to allow users to have an easy installation.
