Description

The HKS Super SQV (Sequential Blow Off Valve) features a unique sequential valve structure paired with a differential pressure control system, allowing it to operate smoothly across a wide range of boost levels, from low to high. Its pull-type relief design ensures consistent and stable performance regardless of boost pressure, making it well suited for modern turbocharged vehicles.

The valve body is constructed from high-quality aluminum using a silver-coated die-cast finish that delivers both durability and a clean, refined appearance in the engine bay. This construction is designed to withstand harsh operating conditions while maintaining long-term reliability.

The secondary valve section utilizes a high-stiffness metal die-cast design, ensuring dependable operation under demanding conditions. For sound enthusiasts, the Super SQV incorporates HKS’s triple fin design, which produces the signature sharp and aggressive “Super Sound.” An optional round fin is also available separately for those who want to fine-tune the sound character.

Features:

  • Pull-type sequential valve structure
  • The new differential pressure control system allows for stable operating ranges from low to high-boost pressures
  • Includes vacuum line filter
  • Includes circlip, T-fittings, and zip ties
  • Includes recirculation connectors
  • Includes factory-like flange to bolt onto the intercooler
  • Includes a pair of polished blow-off valve pipes
  • Includes the HKS Suction Return Hose Kit to allow installation as a recirculation valve
