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

  • 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.
