Reviews of Koyo engine radiator

Koyo Radiator A2807. Great brand and very affordable.

My opinion koyo rad. But any with the heart symbol are favorites.

It’s got an actual Koyo radiator which is a good sign.

My only recommendation after testing several different radiators is to go with Koyo.

My '09 had the bad number, so I bought a Koyo radiator and spent an afternoon swapping it all. That was ~6-7 years ago.

Koyo radiator is the move, it’s all aluminum, no plastic to worry about, the drain plug is legit and there’s a port to add a coolant temp sensor if you want gauges. It has an extra row for better heat exchange and dissipation my only complaint is there’s no aftermarket specific dual cooling fan set up which I feel would do wonders for cooling the engine bay at idle .

I run a 190 in my Honda v6 swapped Miata with a koyorad and it never overheats even in hot weather

I looked at what I bought like 165k and it was KOYO Radiator A1998 for $175 and I'm like 100k miles later and it still looks good. I just wanna change it for preventative maintenance since I'm gonna have my mechanic add the external cooler

I run a Koyo 37mm radiator... and I will hit 200+F under hard driving. Under normal driving, my coolant temps are in between 178-185F.

Koyo N flow. Only rad you’ll ever need. Even though you want to keep it “stock” the OEM style plastic crimped end tank design is a time bomb and should be avoided.
