Viral HKS Super SQV4 Blow Off Valve – Universal

Description

The HKS Super SQV IV (Sequential Blow-Off Valve) features a unique sequential valve structure combined with a differential pressure control system, allowing it to operate smoothly across a wide range of boost levels—from low boost to high boost. Its pull-type relief design ensures stable and consistent performance regardless of boost pressure, helping protect the turbocharger while maintaining rapid response.

Designed to enhance charge response, the Super SQV IV efficiently repeats pressurization and pressure relief during throttle on/off transitions. This makes it well suited for modern turbocharged vehicles that demand fast, reliable boost control and improved drivability.

While the factory recirculation valve operates quietly, installing the HKS Super SQV IV introduces HKS’s signature sharp, high-frequency blow-off sound, clearly announcing its presence. In addition to the sound upgrade, the Super SQV IV enhances engine bay aesthetics with a buff-polished casting pipe designed to complement HKS intercooler piping kits. Together, the distinctive sound and refined appearance significantly increase driving enjoyment.

Features:

• 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.
