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.

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

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
