Whether you use your classic for daily driving or take it to the track, don't overlook the importance of installing an upgraded radiator in their engine.

The inlet and outlets provide precise leak-free connections. Each radiator also includes a magnetic oil drain plug, which effectively removes metal fragments circulating in the cooling system.
