The Mishimoto aluminum radiator for 2023+ Toyota GR Corolla replaces the stock plastic-endtank unit with a larger all-aluminum core that increases core volume by about 51%. Its single-row core uses strutted tubes and louvered external fins to improve heat transfer, and included foam shrouding directs air through the core. Reinforced intercooler mounts and an extended drain port aid serviceability and durability.
