If you're looking to upgrade your Barracuda Parts, look no further! The 1970–1973 Plymouth Barracuda Big Block V8 X-Line Performance aluminium Radiator is an ideal upgrade for the brittle stock Barracuda radiator, and provides your car with enhanced reliability and improved cooling efficiency. Whether you use your 1970 Plymouth Barracuda is your daily driver or you take your 1971 Barracuda to the track on the weekends, many people overlook the importance of installing an upgraded radiator in their engine. A stock Barracuda radiator cannot handle the heat that comes along with having a great deal of horsepower.

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