An ideal upgrade for the brittle stock radiator, the Mishimoto 1967--1969 Pontiac Firebird X-Line Performance Aluminum Radiator provides your car with enhanced reliability and improved cooling efficiency. Whether you want an all-aluminum 1968 Firebird radiator for daily driving or the extra cooling power from a 3-row 1969 Firebird radiator to take to the track, don't overlook the importance of installing an upgraded radiator in your engine. A stock classic car radiator cannot handle the heat that comes along with impressive horsepower. This Firebird 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. Each Firebird radiator also includes a magnetic oil drain plug, which effectively removes metal fragments circulating in the cooling system. As with all our products, every classic car radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
