Engine radiator Koyo or KOYORAD

I went Koyo. For me even with a stock engine its worth it not to have a plastic seam to worry about.

Go for a Koyo and never look back.

Koyorad Aluminum radiator (upgrade): $380 If you got those two parts, it’d save a bulk of the money.

just replaced rad and all soft and hardlines with oem hoses and koyo rad. gives me a lot of reassurance in this LA heat. Great upgrade

The Koyo Rad needs it's own custom cap as the OEM won't fit but man does track city daily without issue and fits OEM fans it's a must have.

My 95 got an aluminum tank Koyorad last month. These aluminum cylinder heads warp too easily to be messing around with cheaper options.

The previous owner had replaced it with a really cheap plastic tank one. It started leaking about a month after I got the car so I spent the money and got an all aluminum Koyo. Its a happy miata now.

Koyo rad hands down best aftermarket replacement.

I would recommend the koyo radiator with stock fans. It’s been 3 years with mine zero issues it’ll run cool in 120 desert.

I would recommend a full aluminum koyo radiator. There are pricy but they fit like OEM and use the OEM fans. 2 years later with 15k and no issues.
