I'm looking to buy a new rad for my 2000 S2000. I've seen the Koyo's on Ebay, and I'm wondering if for one are they worth it and two is it a direct fit for the replacement. The only mods my car has is a AEM V2 intake and HKS exhaust.

 

is something wrong with your stock radiator?

 

Yes it's crushed. I had an accident.

 

I have been interested in these same ones on ebay so Ill be tuning in to what people have to say.

 

There is a number of owner that have installed the Koyo rad. May have been happy with it, and I have not heard any negitive things about them once they are installed.

There is two issues that come to mind with the Koyo.
1. Rad Cap. The OEM cap does not fit and you have to buy one that does.
2. The Fan switch needs a second O-ring to seal properly.

Both Rick and James (owners of Rick's Signature Accessories) run a Koyo. I know they both love it.

 

Ok, thanks for the info. Where can I buy these O rings and what cap fits the Koyo.

contact him and ask him, he can help you get setup with everything you need i'm sure.

 

While I don't have a Koyo radiator for my s2k, I have one on my Prelude. The quality is EXCELLENT, definitely worth the money if you have to replace your radiator anyway.
