I see all brands of good quality aluminum radiators, increased cooling, but any advantage? I sometimes run the car at the track but debating in my head if an upgrade to aluminum radiator is warranted? Any input is appreciated.
If the vehicle isn't running hot and OEM unit isn't leaking or defective, I wouldn't waste money on a radiator as an "upgrade". I've only run OEM radiators in all my mildy-modded Mustangs and Cobras. Never had any cooling issues.
If your car has extensive engine mods and pushing lots of power above stock then it is probably a beneficial upgrade if it has increased capacity over OEM.
