Y8s did some math a good number of years ago about painting intercoolers. It came out to being it does not ******* matter in any way shape or form. Paint it if you want it painted, leave it shiny if you want to show off.

Basically.
But I'd choose anodized vs paint
Layer that sits on top or the latter which is infused into the surface?
The color doesn't matter for hp lmao, but raw alumn oxidation vs a anodized coat.... the anodized coating will last a helluva lot longer
But as for the metal itself, polished alumn may be better for emissivity reflection. Or black with it's epic cool down properties.
Ya know... for that extra .0000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 000000001 HP

You definitely don't want it polished. You want heat to be free to leave. Not that radiation is a primary mode of heat transit for a convection device...
My calcs basically suggested that a thin layer of whatever coating is trivial compared to the aluminum thickness itself. Unless you're talking some crazy thermal insulating stuff like aerogel or nanotubes but honestly, we turbocharge miatas, not space shuttles.
I painted mine black, trying to avoid getting paint on the interior fins since they're pretty thin. I used flat black.
If you can coat it with something that prevents ALO2 forming on the surface and, instead, provides a better thermal conductivity, ... sure you'd get some cooling improvements BUT it also accepts heat from the engine.
