Description
The Mishimoto MMOC-GRC-23TSL is a purpose-built performance oil cooler kit engineered specifically for the 2023+ Toyota GR Corolla’s turbocharged 1.6L G16E-GTS engine. With its 300-horsepower, 3-cylinder powerplant and 10.5:1 compression ratio pushing the oiling system hard, some GR Corollas see oil temperatures soar past 260 degrees — this kit was developed to bring those numbers back down to earth with a dyno-proven, 13-degree average reduction.
At the heart of this Mishimoto oil cooler kit is a 14-row, dual-pass bar-and-plate oil cooler that mounts in the upper grille using direct-fit brackets for maximum airflow without drilling into the body. The kit also adds 0.76 quarts of oil to the system, increasing overall cooling capacity so you can stay on the throttle longer without watching the gauges climb. Pre-assembled black nylon-sheathed -10AN braided stainless-steel lines deliver ample oil flow at high RPM while standing up to street and track abuse alike, making this Mishimoto cooling upgrade equally at home on a daily driver or a dedicated race car.

This oil cooler kit is a direct fit for the 2023–2025 Toyota GR Corolla (chassis code GZEA14) equipped with the G16E-GTS 1.6L turbocharged inline-3 engine. No other vehicles are covered by this application.
