Engine radiator KOYORAD or OEM Toyota
Reviews
I got a Koyorad and 0 issues with overheating with hard driving! Coolant stays at operating temp no matter what.
Pros: no issues with overheating
koyorad on my 400hp Focus and never had over heating issues.
Pros: no over heating issues
Vehicle:
Ford Focus
I replaced my 2010 factory Calsonic with a Kyorad 2807, there were lots of favorable comments on thenewx forum. 18 months later, still going.
Pros: still going after months
Vehicle:
Nissan
Part number: 2807
I had read about people having good luck with the Kyorad brand so that's what I bought.
Pros: good luck with brand
On my Miata with the factory flawed OEM coolant routing, I run a Koyorad 36mm aluminum radiator with OEM fans and it keeps temps a bit cooler than stock.
Pros: keeps temps cooler
Vehicle:
Mazda
I changed out the intake (noise maker but I love it) then everything that connects so the turbo inlet and bpv, charge pipe and a bigger tmic. A engine that can breath will be healthy.
Pros: engine can breath
Cons: noise maker
This specific spot fails on almost every subaru radiator i have worked on.
If you are lucky KoyoRad still has their sale going, I just got an aluminum radiator from my 97 legacy for $180
Pros: aluminum radiator, good price
Vehicle:
Porsche
The radiator you could go OEM or NVA, but Koyorad is proven solid also.
Pros: proven solid
Vehicle:
Nissan
I went with a Koyorad, but for how much I’ve spent, I should have gone with a crossflow (either Supermiata or Flyin Miata). I also did a coolant reroute, which made me really regret not getting a crossflow
Cons: regret not getting crossflow, perceived poor value
I got done years ago for a polished aluminium radiator in a 1985 4th gen Celica.
Vehicle:
Toyota Celica
