Not quite the bargain it used to be. The jump in price makes it easy for me then. Stock it is.

Is this their site:

I've never dealt with Race Consulting before, are they reliable/trustworthy/etc?

Default Re: Koyo radiator experience?

Just thought I'd update this thread if anyone comes looking. I bit the bullet and got the Koyo rad from redline360.

To say the least, I'm quite impressed with this rad.

Fitment is like stock with absolutely no issues. All holes lined up perfectly, and there were provision brackets for everything, from the shroud to the oil cooler housing. The two bottom bolts that hold the oil cooler to the rad were not included, but that was a simple fix.

In terms of performance, noticeable difference. Granted I gave the A/C condenser a wash (it wasn't that gummed up), I noticed a drop of 6-8deg. Going uphill for an extended period of time with the A/C on full blast I used to hit 98-100 which is around the 3rd dot. Same conditions and same hot and humid weather, I'm seeing 92-93 now.
Cruising in 6th, temp is holding around 83 which means the rad is doing its job perfectly well at speed, and sitting in bumper to bumper traffic I'm seeing 86-87 deg.

But more importantly, this new rad is more resistant to rising temps, and the recovery time is much faster, which is what I was really looking for.

Highly recommended, one of the few and rare times I find something better than OE.

I quite fancy one of these, shame the UK prices are a massive rip off compared to US

Thanks for the Koyorad review. I think this will be my upgrade soon.
