For the vehicle having the stock air cleaner.

It achieves the blow-off valve sound even at the Valvetronic engine that does not create the intake manifold negative pressure.


HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles.


  • When the air is vented into the atmosphere, the sharp blow-off sound emphasizes the existence of the SQV by the unique high frequency of the HKS SUPER SQV IV.
  • Changing the material of the charge pipe from the resin (at the stock) to the aluminum improves the durability and reduction of the airflow resistance. (see Fig.)
  • The combination kit including the suction return kit is available for exclusive use in the vehicle equipped with one of the stock air cleaners, HKS Carbon Racing Suction, or HKS Cold Air Intake.
