If you're looking to upgrade your Plymouth Roadrunner parts, look no further! The Mishimoto 1968–1973 Plymouth Roadrunner Big Block V8 Performance Aluminum Radiator provides your car with enhanced reliability, improved cooling efficiency, and is an ideal upgrade for the brittle stock radiator. Whether you use your classic for daily driving or take it to the track, many people overlook the importance of installing an upgraded radiator in their engine. A stock radiator cannot handle the heat that comes along with having a great deal of horsepower.

The Mishimoto Plymouth Roadrunner Big Block V8 Aluminum Radiator is manufactured using durable aircraft-quality aluminum end tanks, precision TIG-welded to an efficient brazed aluminum core. The inlet and outlets provide precise leak-free connections. This Plymouth Roadrunner performance radiator also includes a Magnetic Oil Drain Plug, which effectively removes metal fragments circulating in the cooling system. As with all our aluminum radiators, this Plymouth Roadrunner radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
