This Mishimoto radiator kit overhauls the entire cooling package on the 2020+ Toyota GR Supra and BMW Z4 sDrive30i, replacing the primary and both auxiliary radiators with full aluminum, TIG-welded units. The primary radiator runs a 1.65 in. thick core that increases core volume by 31 percent and external fin surface area by 57 percent, with strutted tubes that resist chassis flex to prevent cracks and leaks. The auxiliary radiators use 1.57 in. thick cores for a 30 percent core volume increase and a 180 percent increase in fin surface area. All three are direct-fit replacements for the slim stock cores and plastic end tanks.
