The Mishimoto aluminum radiator for 1987–1991 BMW E30 M3 manual models is a full-aluminum, direct-fit upgrade that improves cooling capacity by roughly 30%. Featuring a two-row, 1.65-inch brazed core, polished end tanks, and TIG-welded construction, it increases fluid capacity and heat dissipation for street or track duty. Installation is OEM-style with no cutting required, making it a practical replacement for aging stock radiators.
