The Mishimoto Performance Oil Cooler Kit brings the 2023+ Toyota GR Corolla's oil temperatures under control. The turbocharged 1.6L three-cylinder runs high compression and pushes oil temps past 260 degrees under hard use. This kit mounts a 14-row dual-pass bar-and-plate cooler in the upper grille on direct-fit brackets for a dyno-proven 13-degree average reduction in oil temps and adds 0.76 quarts of oil to the system. Pre-assembled black nylon-sheathed -10AN braided stainless-steel lines ensure ample flow. The thermostatic sandwich plate suits daily drivers and cold climates. Backed by the Mishimoto Lifetime Warranty.
