HKS Super SQV4 Universal Blow Off Valve Assy – Standard & Black Edition

HKS Super SQV4 Universal Blow Off Valve (Standard & Black Edition)

Why we trust the SSQV4:

• Sequential Valve System: It uses a primary small valve for fast response and a secondary large valve for maximum flow. It doesn't matter if you're creeping in traffic or wide open on the dyno, it vents exactly when it needs to.
• Leak-Proof Design: Unlike a lot of cheap valves that rely on fragile diaphragms, the SSQV4 uses a pull-type relief design. The higher the boost pressure, the tighter it seals. You don't have to worry about boost leak issues at idle or under load.
• That Signature Sound: Yeah, it’s loud. It’s that sharp, high-frequency chirping sound that sets HKS apart from the "whoosh" of standard piston-type valves. It’s aggressive, and it’s recognizable.
• Build Quality: You hold this thing in your hand, and it feels like a precision instrument. The cast aluminum frame and stainless steel components are built to handle heat and vibration without cracking or failing.

Features & Benefits

• Universal Application: Because this is the universal kit, it’s designed to be adaptable. Whether you're running a custom piping setup or need to replace a failing factory unit, this gives you the flexibility to install it how you need it.
• Adjustable Response: It doesn’t need a spring adjustment every time you change your boost level. It’s designed to be self-adjusting to a degree, making it much more "set it and forget it" than older designs.
• Sleek Finish Options: Go with the classic polished Standard look, or step up to the Black Edition if you’re trying to keep that "stealth" look under the hood.
• Reliability: These valves are legendary for lasting years. It’s one of those parts you buy once and don't have to worry about for the life of the build.

Vehicle Fitment

• Standard Part Number: 71008-AK001

• Compatibility: This is a universal kit. It’s compatible with virtually any turbocharged application, provided you have the correct flange or mounting adapter for your specific piping kit. (Pro Tip: Since this is universal, make sure you have the right flange adapter for your intercooler piping before you start the install. If you’re not sure what flange you need, just hit us up and we can point you in the right direction.)
