The Triple Fin design on the valve produces a “Super Sound, “ adding a dynamic and aggressive aural experience to my daily commute.

However, I did encounter a minor issue with the Pull-Type relief design. At high boost pressures, it seemed that the valve could be a bit noisy at times. Nevertheless, it didn’t impact the overall performance or operation of the valve.

🔗Triple Fin Design HKS Super SQV4 Blow Off Valve

hks-super-sqv4-blow-off-valve-kit-1

As a car enthusiast, I can vouch for the HKS Super SQV4 Blow Off Valve Kit being a game-changer in my daily driving experience. This blow off valve kit serves as a direct replacement to the factory blow off valve in your vehicle, saving you from potential boost leaks and enhancing your turbocharger’s performance.

One of the standout features of this kit is its pull-type sequential valve structure. It works efficiently to relieve excess boost between shifts and under deceleration, ensuring a stable operation range, from low to high-boost pressures. I have experienced first-hand the quick reduction in pressure, which really makes a difference when driving enthusiastically.

The kit also comes with all necessary adapters, clamps, hoses, and fittings that make installation a breeze. I appreciate the attention to detail HKS puts into their kits to ensure a seamless installation process.

This product is not without its minor drawbacks. After some time, you may need to do light maintenance on the valve itself, as it might get stuck open for a couple of seconds before operating normally. However, once lubed, it has been functioning properly again. Additionally, the instructions provided by HKS could use some improvement, so it’s best to rely on YouTube tutorials for a smoother installation.

Overall, the HKS Super SQV4 Blow Off Valve Kit is a must-have for any car enthusiast who wants to optimize their turbocharger’s performance, while also enjoying the unique sound profile it brings to the table. Just make sure you’re prepared for the occasional maintenance and a slight learning curve with the installation instructions.

Ever since I installed the HKS Super SQV Racing Blowoff Valve, my car has been a completely different beast, in a good way, of course. This badass piece of machinery is specifically designed for high-horsepower applications and boy, does it deliver. Not only does it handle extreme pressure and airflow discharge volume so effortlessly, but it also looks every inch the boss.

What really stands out is its large single-stage aluminum pull-type valve. It’s like having a tiny superhero working tirelessly to ensure every drop of boost is utilized and nothing is wasted. And speaking of boost, the valve accommodates up to 3.0 bar (43.44psi), which, as someone who knows their cars, means my engine is in safe hands.

One might think that all this power would be tough to manage, but the Super SQV Racing Blowoff Valve was engineered with such precision that it feels like magic. It seamlessly integrates with the circular mounting flange and the beautifully crafted billet aluminum construction, providing a perfect seal and exceptional flow.

But what makes this HKS blow off valve really shine is the packaging. The bubble wrap they used is so thick, it’s like it’s wrapped in a mini-fortress to protect the valve. And the fact that the valve comes with two recirculation fittings in 19mm and 29mm just added a cherry on top.

However, like any product, there are those tiny drawbacks that you can’t avoid. The installation does take a bit more time than expected. But hey, if you’ve got the time and the passion for cars, I say, go with the flow. And let me tell you, the sound you get after installation — it’s a symphony.
