Mishimoto’s X-Line aluminum radiator for 1967–1969 Pontiac Firebird brings modern cooling to classic applications. Offered in options such as an all-aluminum single-pass layout for daily driving or a 3-row core for extra track-capable cooling, it uses aircraft-quality aluminum end tanks, precision TIG-welding, a billet fill neck and a magnetic oil drain plug to protect the cooling system.
