Super SQV4 Blow Off Valve

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles.

High Quality Aluminum Die-Cast Body - Silver-coated aluminum die-cast body. Combines the ultimate in looks and durability in the engine compartment.

High Stiffness Metal Die-Cast Valve - Secondary valve main portion is made of die cast metal. Reliable operation with beautiful looking.

Triple Fin design produces "Super Sound" - Triple Fins set at the center of the funnel produces a dynamic and aggressive sound. An optional special Round Fin can be purchased separately for sound tuning.

Pull-Type Relief Valve Operation - The Pull-Type valve operation offers more precise relief of excess boost and is compatible for a wider range of boost pressure compared to typical push-type blow off valves.

Primary Valve (Small) - Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure.

Secondary Valve (Large) - This valve combined with the Primary Valve from the sequential dual valve structure. Optimal blow-off operation from how to high boost ranges without leaking.

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.

  • Accelerator ON
    Valves Closed

    As pressure rises in chamber C, pressure is applied to both the Primary and Secondary valves. The higher the boost pressure, the more pressure is applied to the valves, preventing leaks.

  • Accelerator OFF
    Primary Valve Opens

    Throttle lift creates a pressure difference between chambers A & B, opening the primary valve bypassing the secondary valve. this creates the initial discharge.

  • Accelerator OFF
    Secondary Valve Opens

    When pressure difference in chambers A & B reach a maximum, the Primary Valve pulls the Secondary Valve open, creating a secondary discharge.

Pull-Type blow off valves will work for any turbocharged vehicle, from stock to highly tuned.

Typical push-type blow off valves require spring load settings for each vehicle specification. If the spring load setting is too low, the valve may leak under high boost and the desired boost setting may not be reach. If the spring load setting is too strong, it may not open at low boost. The Super SQV will operate under any boost pressure setting without leaking.

Great Keyboard Case!
Color: Pink
Bought this for the wife for Mother’s Day since she needed a new keyboard and case. She used my old Magic Keyboard but constantly was tired of taking her iPad off, just to rotate it. Bought this and she loves it. Very durable, even with our 2 year old playing with it. Keyboard is bright and is good to use. Just a Bluetooth keyboard setup and it’s all good to go! Definitely great value for the money and something highly recommended for those with an iPad Air or Pro.

Super cute and soft!
Color: Pine Green, Color: Pine Green
I really like this case. I was surprised by how soft it is! It arrived in perfect condition (just like the photos), no smell, keyboard worked. I followed the sellers instructions to charge before use. I gave it one less star because personally don’t care about the keyboard, it’s a little on the slower side when using the mousepad or typing. I didn’t have any issues with connecting. It was an easy setup. I’d suggest you spend the money for a laptop or a true keyboard if you need it. This is more for looks. If it wasn’t for the quality of the case, I’d probably return.

Good protection for my ipad
Color: Sky Blue
Flap to close is magnetic, so it stays closed. Has a spot for the open for the ipad. Keyboard is a handy feature to have, and love that it lights up.
