We are pleased to bring you an OEM replacement radiator that meets all of the proper OE requirements. This radiator is a copper core radiator with plastic end tanks. It has a built in transmission cooler for automatic transmission models. The radiator is compatible with all models and years of the Mitsubishi 3000GT and Dodge Stealth. What really sets this radiator apart from other “OE Spec” radiators is the use of a copper core. This core is more efficient at heat transfer than an aluminum core. OEM radiators used copper cores for this very reason. You get a more efficient radiator without having to go with a thicker radiator core when using aluminum.
