Mishimoto Performance Aluminum Radiator - BMW E30 M3 Manual (1987-1991)

Mishimoto's performance aluminum radiator is a direct-fit upgrade for the 1987-1991 BMW E30 M3 with manual transmission, giving the S14 engine cooler, more efficient running and around 30 percent greater cooling capacity over the stock radiator. It uses a two-row, 1.65-inch-thick brazed aluminum core with durable TIG-welded construction and polished end tanks, an ideal replacement for an aged, clogged, or leaking factory radiator.
