Mishimoto Performance Aluminum Radiator - BMW E46 M3 3.2L S54 (2001-2006)

Mishimoto's performance aluminum radiator is a complete bolt-in upgrade for the 2001-2006 BMW E46 M3 (3.2L S54), built for the demands of track use. An extremely dense core with more coolant tubes and a tight fin composition adds heat-transfer contact points, delivering a 32 percent increase in coolant surface area, 15 percent more air surface area, and 25 percent more coolant capacity. TIG-welded high-quality aluminum end tanks join a 100 percent brazed aluminum core, and it fits the stock clutch fan and shrouding with no modification.
