Engine radiator MISHIMOTO or Koyo

Mishimoto makes a really good aluminum replacement, highly recommend

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

I would get a Mishimoto all aluminum radiator, superb cooling and you won’t have to worry about plastic failing again.

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.

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”.

I’ve been using the same one on my skyline for nearly 10 years and lately the coolant has been brown. Mishimoto radiators are good enough

Bought it for my coyote swapped F100 and there was a hole in it from the start. Rewelded the whole thing because wasn’t worth the return when I can just do it myself. Welds just looked like someone just started child labor and it was their first day on the job. Wouldn’t buy one again if I had too.

my Mishimoto leaked/falied apx 10-11 years after I bought it. and keep the receipt, or your lifetime warranty will not be valid
