The HKS Super SQV (sequential blow-off valve) uses a unique two-stage sequential valve structure using a primary valve and a secondary valve, and uses a differential pressure control system to adjust the range from low to high turbocharging. This blow-off valve achieves delicate pressure control over a wide range of operating ranges. [Compatibility] Subaru Impreza Model: GH8 Engine: EJ20x Year: 07/06-11/12 "S-GT" Subaru Legacy B4 Model: BL5 Engine: EJ20x Year: 03/05-09/05 Used with R type intercooler When doing so, a separate φ19/l=500mm hose is required. Subaru Legacy Touring Wagon Model: BP5 Engine: EJ20x Year: 03/05-09/05 When using with R type intercooler, a separate φ19/L=500mm hose is required.

HKS SUPER SQV (Sequential Blow-off Valve) uses HKS's unique two-stage sequential valve structure using a primary valve and a secondary valve, and uses a differential pressure control system to adjust from low to high supercharging ranges. This enables delicate pressure control over a wide range of operating ranges. In addition, the ``reliefless operation method'', which is different from the structure of a general blow-off valve, suppresses relief during turbocharger supercharging and maximizes charge response when repeatedly supercharging and releasing by throttle ON/OFF. It is now possible. SQV IV supports all turbo cars in a new dimension. Precautions for use When using with R type intercooler, a separate φ19/L=500mm hose is required.
