Kelford KVS97 Valve Spring Set for Subaru WRX Version 3 - 4 STI, High Performance - KVS97
Kelford KVS97 Valve Spring Set for Subaru WRX Version 3 - 4 STI, High Performance - KVS97 - Image 2

If you?re diving into the world of performance upgrades for your Subaru WRX Version 3-4 STI, you?ve got to check out the KVS97 Kelford Valve Spring Set. These aren?t just any valve springs; they?re designed to help your engine breathe better and perform at its peak. With a seat pressure of 87 lbs at an installed height of 42.00 mm, these springs are built to handle some serious RPMs without breaking a sweat.

Now, a quick heads up: if you?re using the OEM STi retainers, you?ll need to do a little machining to get these springs to fit just right. It?s a minor tweak, but it?s worth it for the gains you?ll see. Once they?re in, you can expect improved valve control, which means better throttle response and more power when you need it. Plus, they can help prevent valve float at higher RPMs, so you can push your WRX without worrying about losing that precious power.

These springs are a solid upgrade for anyone looking to get more out of their ride. Whether you?re hitting the track or just want a more responsive daily driver, the KVS97s will make a noticeable difference. Trust me, once you feel the difference in your engine?s performance, you?ll wonder how you ever drove without them!
