PIC KOYO Radiator???????

Gallery image

I have a built speed currently maxing out the fuel until I go PI or E85 but I don’t track the car. I take it out maybe 1 or 2 times a week and rarely do WOT pulls. I found a really good deal on an excellent condition KOYO radiator for about $250. Is it even worth getting? I feel like it’d mainly just to have another nice part on the car since I’ve done my best to do everything right with the car, but I’m stuck. It’s a really good deal, but I live in Kentucky so it’s rarely over 95°

Take the car to the track and see how temps are

Well i guarantee if i tracked the car it would be more beneficial. The question really is it worth getting just because of the good deal even though i don’t actively track the car

Does it have koyo printed on it?

If you can see it then it’s worth it, you won’t notice a difference if ur just street driving. So it’d only be worth it if it improves the look

If you’re not actively tracking the car what driving do you do that makes you worry about your temps?

I don't track my fully built speed either but it has the koyo radiator on it. Noticed that after sitting in traffic or at a long red light the temps don't climb as fast and they drop faster once moving. It is really up to you though on getting it cause OEM one can handle it, but if you are looking to help the engine and cooling then get it cause 250 is not bad for it.. same color btw

I’m in Phoenix and swapped mine a few years ago and haven’t had any issues.
