M3’s dont really have a rep for overheating unless that is you’ve thrown on a few significant modifications. And if you have an E46 M3 its almost impossible to not modify it! Its true there was a study on it… Anyway more power means more efficient cooling and everyone’s favorite radiator manufacturer has an application for the E46 M3 that will improve cooling by 30% which isn’t a number to sneeze at!
