Supertech Dual Valve Spring for Acura Honda H22A1/H22A4 1993-2015, 29.65mm OD - SPR-H1005D

If you're looking to give your engine the boost it deserves, check out the Supertech Valve Springs. These aren't just any springs; they’re crafted from a top-notch Superclean Chrome Silicon Vanadium Steel Alloy. What does that mean for you? Well, it translates to serious performance and durability, especially when you're pushing those RPMs. I've had my fair share of experience with different valve springs, and let me tell you, the memory these springs have is impressive. You can really feel the difference in performance when you're on the throttle.

These springs are designed with precision in mind. Supertech has put a lot of thought into the wire stress levels, making sure they stay within safe limits. That’s crucial if you’re planning to take your ride to the limits. They’re built to last, even when the heat is on—literally. Whether you're hitting the track or just cruising around, these springs hold up under pressure.

Now, let’s talk specs because I know that’s what really matters. These are dual springs, which means they’ve got a solid design to handle the demands of high-performance engines. The outer spring diameter is 29.65mm, while the inner comes in at 20.50mm. They’ve got a seat pressure of 93lbs at 35.5mm, and when it’s time to open up, you're looking at 239lbs at just 12.5mm. Max lift is at 14.80mm, and they won’t bind until you hit 20.70mm. Pretty impressive, right? Plus, the rate is 11.50mm, which gives you that extra edge you need.

These springs fit a range of models, so if you’re driving an Acura RSX from 2002 to 2006, or a Honda Accord from 2003 to 2015, you’re in luck. They also fit several other popular models like the Honda Civic (2002-2011), CR-V (2002-2012), and even the Prelude from ‘93 to 2001. It’s a solid option for anyone looking to upgrade their ride.

In short, if you want to enhance your engine's performance and reliability, these Supertech Valve Springs are a solid choice. They’re built for the long haul, and you’ll definitely notice the difference when you hit the gas.
