Koyo is definitely one of the best available as a stock replacement. They make 2. The n flow is a little harder to fit but is “better”.
Koyo rad is top tier, as I’ve used them on all my drift builds.
Held out for the koyorad and it's the same size as stock and went in with no troubles.
I have a koyo radiator in my na6 with stock fan on it and it has no clearance issues. Probably wasn’t necessary for me currently but I’m going turbo after I spend more time driving it na so figured why buy twice and just went for the koyo.
My 2012 Sti with a Koyo aluminum radiator makes plenty of heat even down below 0°F
You can get a koyo radiator for like $160 bucks. I have an Avalon that looks identical under the hood. If it takes you more than 1 hours start to finish something went wrong.
I went to the same thing this past summer(vegas) until I changed to koyo rad.
the Koyo certainly looks much better. You won't notice any difference in cooling between the two.
I'd go with Koyo for price and ease of install. My reservoir hose nipple broke on my OEM radiator (OEM has plastic tanks) so I went with all aluminum for durability. My RX-8 also only drives on race tracks, so the extra cooling is nice.
I'd replace it with a fully aluminum one just because of that pesky plastic nipple that's prone to breaking. Koyo makes a good one.
