If you’re looking to upgrade your Dodge Challenger parts, look no further. The Mishimoto 1970–1974 Dodge Challenger Big Block V8 X-Line Performance Aluminum Radiator is an ideal upgrade for the brittle stock Challenger radiator, and provides your car with enhanced reliability and improved cooling efficiency. Whether you use your 1970 Dodge Challenger is your daily driver or you take your 1971 Dodge Challenger to the tack on the weekends, many people overlook the importance of installing an upgraded radiator in their engine. A stock Challenger radiator cannot handle the heat that comes along with having a great deal of horsepower. The Mishimoto Dodge Challenger 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 Dodge Challenger radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
