A full-aluminum direct-fit performance radiator for the 2023+ Toyota GR Corolla, whose turbocharged 1.6L three-cylinder puts heavy demand on the cooling system on track and in traffic. It replaces the stock plastic-end-tank unit with a core 51 percent larger, holding more coolant and dissipating more heat. The single-row core uses strutted tubes for greater effective cooling area and added rigidity against impacts, with louvered external fins to improve heat transfer.
