HKS Super SQV4 Sequential Blow Off Valve 71008-AK001
HKS Super SQV4 Sequential Blow Off Valve 71008-AK001
The HKS Super SQV4 features a unique sequential valve structure and a differential pressure control system that allows for a broad operating range from low to high boost. Its pull-type relief design ensures exceptionally stable operation regardless of boost pressure levels, maximizing charge-response during aggressive throttle transitions.
Crafted with a high-quality die-cast aluminum body and stiff metal valve, this blow-off valve delivers both rugged durability and a clean engine bay appearance. The signature triple-fin center design produces a distinct, high-frequency sound while the dual-valve sequential mechanism guarantees linear response across all driving conditions.

Highlights
- 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.
Materials & care
Constructed from die-cast aluminum and high-stiffness metal components. Keep free from excessive road grime and inspect vacuum hoses periodically to maintain optimal valve responsiveness.
