If you're looking to upgrade your Roadrunner parts, look no further! This Mishimoto 1972-1973 Plymouth Roadrunner Small 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 1973 Plymouth Roadrunner as a daily driver or take your 1972 Roadrunner down to the track on the weekends, 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 Small 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 Roadrunner radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
