If you're looking to upgrade your Plymouth Roadrunner parts, look no further! The Mishimoto 1968–1973 Plymouth Roadrunner Big Block V8 X-Line Performance Aluminum Radiator is an ideal upgrade for the brittle stock Roadrunner radiator, and provides your car with enhanced reliability and improved cooling efficiency. Whether you use your 1970 Plymouth Roadrunner as a daily driver or take your 1969 Roadrunner to the track, many people overlook the importance of installing an upgraded radiator in their engine. A stock Roadrunner radiator cannot handle the heat that comes along with having a great deal of horsepower.

The Mishimoto Plymouth Roadrunner Big Block V8 X-Line 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 performance aluminum radiator also includes a Magnetic Drain Plug, which effectively removes metal fragments circulating in the cooling system. As with all our products, this Plymouth Roadrunner radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
