Aftermarket Radiator UpGrade or factory?

Most all of today’s radiators comes with plastic tanks. The hot tank is the usual that will fail...most crack to then leak

Plastic will not last as long as metal. More so on high temp applications.

There are all metal radiators, but most are either custom...or...stocked as a speciality. Meaning expensive. Therefore they only stock them for the most popular brands/models

Figment metrics are to the OEM radiator and to oversized cores

Cores...are the heat exchanger (AKA...thermal/heat rejection area), portion of the thermal rejection system. A liquid to gas

Surface area the most important, but the other attributes play into performance of the radiators

Tubes...round, semi-flattened, and oval are the most common. Cheapest is round

Laminar flow. Both liquid and air is NOT a good thing...flow in layers...closest hottest...next layer cooler..etc. turbulence to foil laminar flow will have cooler air/liquid touch...to cool better

The better ones will have fins on both exterior surfaces and internal surfaces...the mix it up (breaks up laminar flow)

Staggered tubes has the air flow change direction...so better thermal rejection

Finally...the number of tube rows...normally referenced as “2 core”, “4 core” etc...

These are multiplexed together to make up mud hen up to performance radiators

Hope this will help the OP compare apples to apples...
