The HKS Super SQV4 Sequential Blow Off Valve offers a unique valve structure and differential pressure control system that allows for a wide operating range of boost levels. Its Pull-Type relief design ensures stability no matter the amount of boost pressure. This revolutionary valve maximizes charge-response by repeatedly pressurizing and releasing air through throttle on and off, making it a valuable addition to any turbocharged vehicle. Unlike factory recirculation valves, the HKS Super SQV IV produces a distinct and sharp high-frequency sound, adding a new level of performance and enhancing the engine compartment's appearance. The buff-polished casting pipe included with the valve matches perfectly with the appearance created by the HKS Intercooler Piping Kit, making both the sound and appearance of the Super SQV IV a thrilling addition to any ride.



  • High Quality Aluminum Die-Cast Body - Combines the ultimate in looks and durability in the engine compartment.
  • High Stiffness Metal Die-Cast Valve - Reliable operation
  • Triple Fin Design - Triple Fins set at the center of the funnel produces a dynamic and aggressive sound.
  • Pull-Type Relief Valve Operation - More precise relief of excess boost and is compatible for a wider range of boost pressure
  • Primary Valve (Small) - Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure.
  • Secondary Valve (Large) - Combined with the Primary Valve to provide optimal blow-off operation from low to high boost ranges
  • Dual Valve Structure, Sequential System - At low boost ranges the Primary Valve opens, and at high boost ranges the Secondary Valve also opens, resulting in linear response and optimal blow-off operation at all boost levels.



Please Note: Compatible with a vehicle with Intercooler Piping Kit (13002-AH001)
