The HKS SQV (Single Quad Valve) Blow-Off Valve (Part Number: HKS 71008-AH009) is a performance enhancement accessory designed specifically for the 2017-2021 Honda Civic Type R (FK8) with the K20C engine. This blow-off valve offers significant improvements over the stock component, providing better boost response, increased reliability, and enhanced engine performance.
The HKS SQV Blow-Off Valve is a twin solenoid, vacuum-controlled device, which means it utilizes vacuum lines from the intake manifold to operate. It's designed to release excess boost pressure from the intake system during sudden throttle closures, like when downshifting or lifting off the throttle during hard acceleration. By efficiently venting this pressure, the SQV helps maintain optimal boost pressure and boost recovery for improved engine responsiveness and driving performance.
This HKS blow-off valve is manufactured using high-quality materials, including a durable anodized aluminum housing and resilient rubber diaphragms. The vacuum lines are connected using OEM-style fittings, ensuring a perfect seal and seamless integration with the factory intake system. The blowing characteristics can be easily adjusted using an Allen key, allowing users to fine-tune the valve's performance according to their driving preferences and track conditions.
The HKS 71008-AH009 SQV Blow-Off Valve is a premium upgrade for WRD (Wide Range Driving) applications, track days, and competition use on the 2017-2021 Honda Civic Type R FK8. With its vacuum-controlled design and adjustable blowing characteristics, this blow-off valve not only enhances engine performance but adds a touch of racing style to your vehicle as well. Its impressive reliability and durability are hallmarks of HKS, delivering superior functionality and longevity compared to the stock blow-off valve.
The HKS 71008-AH009 SQV (Supersonic Recirculating Blow-Off Valve) is a popular aftermarket upgrade for the Honda Civic Type R FK8, particularly for those seeking to enhance their vehicle's performance. This article will discuss both the advantages and disadvantages of investing in this component.
II. Pros of HKS 71008-AH009 SQV1. Improved Turbo Responsiveness: By maintaining a precise level of boost pressure during acceleration, the SQV helps to reduce lag, thus delivering a more responsive and spirited driving experience.
2. Enhanced Engine Sound: The blow-off valve produces a desirable secondary exhaust sound that enhances the overall engine note, especially noticeable during downshifts and throttle lifts.
3. Enhanced Durability: HKS, a renowned performance parts manufacturer, designs their blow-off valves with high-quality materials and engineering, promising long-lasting performance under high-performance driving conditions.

Pull-Type blow off valves will work for any turbocharged vehicle, from stock to highly tuned. An optional special Round Fin can be purchased separately for sound tuning. The Super SQV will operate under any boost pressure setting without leaking. Its Pull-Type relief design ensures stable operation regardless of the amount boost pressure.
HKS Super SQV Blow Off Valve, For, 2017 21 Honda Civic Type-R FK8 K20C, Part Number: 71008-AH009, Sequential Valve uses a unique sequential valve structure and differential pressure control system, which allows for broad operating range from low boost to high. Super SQV IV significantly increases its presence and improve the engine compartment appearance. Combines the ultimate in looks and durability engine compartment. 3.Secondary Valve Large This valve combined with the Primary from sequential dual structure.
Factory re circulation valve sound cannot be noticed, but once HKS Super SQV IV is installed, its unique sharp high frequency demonstrates existence. Reliable operation with beautiful looking. 1.High Quality Aluminum Die-Cast Body Silver-coated aluminum die-cast body. If the spring load setting is too low, valve may leak under high boost and desired not be reach.
2.Primary Valve Small Lift off the throttle, and primary valve instantly opens, quickly discharging initial excess boost pressure. Typical push-type blow off valves require spring load settings for each vehicle specification. By both the sound and appearance, Super SQVIV increases fun to drive. To match with the appearance created by HKS Inter cooler Piping Kit, buff-polished casting pipe is included.
Dual Valve Structure, Sequential System At low boost ranges the Primary opens, and at high Secondary also resulting in linear response optimal blow-off operation all levels. If the spring load setting is too strong, it may not open at low boost. 3.Triple Fin design produces Super Sound Triple Fins set at the of funnel a dynamic and aggressive sound. 2.High Stiffness Metal Die-Cast Valve Secondary valve main portion is made of die cast metal.
1.Pull-Type Relief Valve Operation The Pull-Type valve operation offers more precise relief of excess boost and is compatible for a wider range pressure compared to typical push-type blow off valves. Optimal blow-off operation from how to high boost ranges without leaking.
