Mishimoto Performance Aluminum Radiator - Toyota GR Supra & BMW Z4 / 330i 3.0L (2019+)

This Mishimoto performance aluminum radiator is a direct-fit upgrade for the 2019+ Toyota GR Supra and B58/B48-powered BMW Z4 and 330i, replacing the slim stock core and plastic end tanks with a full aluminum, TIG-welded construction. The 1.65 in. thick core increases core volume by 31 percent over stock and expands external fin surface area by 57 percent for greater heat dissipation, especially when paired with the Mishimoto Performance Auxiliary Radiators. Strutted tubes run throughout the core to resist chassis flex and reduce the risk of breaks or leaks.
