The Mishimoto performance aluminum radiator fits 2023+ Toyota GR Corolla models including Core Premium Morizo Edition and Circuit Edition. This direct replacement features a 51 percent larger core to hold more coolant and dissipate heat from the 300 horsepower 1.6L turbo engine during track sessions or stop-go traffic. Engineered to maintain lower coolant and oil temperatures it prevents overheating seen in stock plastic end tank units.
