Rating 4.0

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

KOYORAD Engine radiator

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

KOYORAD Engine radiator

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

Nissens Engine radiator

  • Overheating:
Rating 1.0

The ~2014 Nissens, with the 15 round tube design just doesn't cut it. From what I can tell the car would've come with the 30 flat tube design. The Nissens just doesn't have enough surface area. On a hot day, with the AC going and highway speeds it just couldn't keep up.

Cons: insufficient cooling, low surface area
Vehicle: Audi
