Mishimoto's performance aluminum radiator is a direct-fit upgrade for the manual-transmission BMW 135i, 335i, 335is, 1 Series M, and Z4 (2007-2013, N54/N55 inline-six). It pairs TIG-welded end tanks with a 100 percent brazed two-row aluminum core and CNC-machined quick-disconnect inlet and outlet connections that mate to the stock hoses, delivering a 35 percent increase in coolant capacity over the failure-prone stock plastic radiator. A brushed aircraft-aluminum finish and an included magnetic drain plug with dowty seal round out the package.
