More Info:
The 2023+ Toyota GR Corolla is a modern track beast, offering the versatility of a hatchback, fuel efficiency from a 1.6L 3-cylinder engine, and a powerful 300 horsepower. Toyota’s Gazoo Racing division crafted the GR Corolla with excellence, but there's still room for improvement.

With 100 HP per cylinder, the engine generates significant heat, particularly in the form of high oil temperatures. The turbocharger and 10.5:1 compression ratio push the oiling system hard, often causing oil temps to rise above 260 degrees. To manage this, Mishimoto has created a performance oil cooler kit specifically designed for the GR Corolla’s high-energy engine.

This kit includes everything needed to control oil temperatures. A 14-row dual-pass bar-and-plate oil cooler, mounted in the upper grille with direct-fit brackets, enhances airflow and results in an average 13-degree drop in oil temperatures, adding 0.76 quarts of oil to the system. Pre-assembled -10AN braided stainless-steel lines are included for easy installation and optimal oil flow. The kit is available with a thermostatic oil filter sandwich plate for daily drivers and cold climates, or a non-thermostatic version for track cars or hot environments. Backed by Mishimoto’s Lifetime Warranty, this kit ensures you can push your GR Corolla with confidence.
