Supertech Dual Valve Spring for Honda Prelude H22A1 | H22A4 1992-2001, Chrome Silicon Alloy - SPR-H1000D

If you're looking to upgrade your Honda Prelude's performance, you might want to check out the Supertech Valve Springs. These bad boys are crafted from a top-notch Superclean Chrome Silicon Vanadium Steel Alloy. What does that mean for you? Well, it translates to serious durability and performance, especially when you're pushing those RPMs. I've had my share of experiences with various springs, and let me tell you, the memory on these springs is impressive. They really hold their shape, which is crucial when you're chasing higher performance.

Now, let's talk about the design. Supertech has put in the work here. These valve springs are computer-designed to keep wire stress levels in check, ensuring they don't go overboard. That means you're getting a product built for the long haul, even when you're pushing your engine to its limits. I've seen plenty of parts fail under pressure, but these springs are made to withstand extreme conditions without batting an eye.

Here’s a quick rundown of the specs if you're into that kind of thing:

  • Type: Dual Spring
  • Outer Spring OD: 29.65mm
  • Outer Spring ID: 21.85mm
  • Inner Spring OD: 20.50mm
  • Inner Spring ID: 15.50mm

  • Retainer: RET-K20A2/T2 + SEAT-H1020DS

For fitment, these springs are specifically designed for the Honda Prelude models from 1992 to 2001. If you’ve got a Prelude with the H22A1 or H22A4 engine, you’re in luck—these springs will fit like a glove.

So, if you're serious about getting more out of your ride, consider the Supertech Valve Springs. They’re a solid investment for anyone looking to push their engine performance without worrying about reliability.
