If you're looking to upgrade your Plymouth Barracuda parts, look no further! The Mishimoto 1970–1973 Plymouth Barracuda 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.

The inlet and outlet provide precise leak-free connections. This Plymouth Barracuda 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 Barracuda radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
