More from Mishimoto:
The 2023+ Toyota GR Corolla produces 300 horsepower from a 1.6L, 3-cylinder engine, pushing the limits of its cooling system. Prolonged track sessions or traffic can cause oil temperatures to exceed 260 degrees, as the stock liquid-to-liquid oil cooler relies on coolant to regulate oil temps. If the radiator struggles, so will the oil cooler. Mishimoto’s performance aluminum radiator is designed to keep your GR Corolla's engine cool.

This all-aluminum radiator features a core that’s 51% larger than the stock plastic one, allowing for more coolant capacity and better heat dissipation, reducing overall stress on the cooling system. The strutted tubes enable a single, wider tube with greater effective cooling area, improving core rigidity to prevent leaks from impacts. Louvered fins enhance airflow, maximizing heat transfer, while included foam shrouding ensures cool air flows through the core.

Durability and serviceability are key aspects of this radiator's design. Reinforced intercooler mounts allow for larger intercoolers, and an extended drain port with a slotted drain plug makes draining mess-free. As with all Mishimoto products, this radiator is backed by the Mishimoto Lifetime Warranty.
