Mishimoto's performance aluminum radiator is a direct-fit upgrade for manual-transmission BMW E46 non-M models (323i, 325i, 328i, 330i and Z4, 1999-2009), outlasting the weak stock plastic radiator. It uses a large two-row, 100 percent brazed aluminum core with polished end tanks for a 20 percent increase in coolant capacity, 18 percent more coolant surface area, and 41 percent more air surface area. CNC inlets and outlets mate perfectly to the stock quick-disconnect hoses for a clean, no-modification installation.
