HKS Super SQV Sequential Blow Off Valve for Turbocharged Vehicles

If you're looking to upgrade your turbocharged vehicle, the HKS Super SQV (Sequential Blow Off Valve) is designed for performance and reliability. This advanced valve features a unique sequential structure and a differential pressure control system, making it suitable for a wide range of boost levels—from low to high. Whether you drive a stock model or a highly tuned beast, the Super SQV ensures optimal operation without leaks.

Key Features

  • High-Quality Aluminum Die-Cast Body: The silver-coated aluminum body not only looks sleek but also offers exceptional durability in your engine compartment.
  • Sturdy Metal Die-Cast Valve: The secondary valve is crafted from die-cast metal, ensuring reliable performance while maintaining an attractive appearance.
  • Triple Fin Design: Enjoy a dynamic and aggressive sound thanks to the triple fins positioned at the center of the funnel. For those wanting to customize their sound, an optional Round Fin is available separately.
  • Precision Pull-Type Relief Valve: This design allows for more accurate release of excess boost, accommodating a broader range of boost pressures compared to standard push-type valves.
