Mishimoto Oil Cooler Kit for Toyota GR Corolla '23+

The 2023+ Toyota GR Corolla is a track weapon for the modern world. Combining the practicality of a hatchback, the fuel efficiency of a 3-cylinder 1.6L engine, and 300 horsepower, the GR Corolla can do it all. Toyota's Gazoo Racing department didn't hold back when they designed the GR Corolla, but they did leave a little room for improvement.

Any time you're pushing 100 HP per cylinder, the engine is going to be producing a lot of heat. For the GR Corolla, that heat rears its head in the form of high oil temperatures. The fast spinning turbo and high 10.5:1 compression ratio means the oiling system is doing a lot of heavy lifting, and that results in oil temps soaring over 260 degrees for some. To help cool the GRC's spunky engine, Mishimoto has developed a performance oil cooler kit fit for the Gazoo Racing spirit.

Our 2023+ GR Corolla oil cooler kit includes everything you need to get your GRC's oil temps under control. This kit mounts our 14-row dual-pass bar-and-plate oil cooler in the upper grille using direct-fit brackets. This allows more airflow to the cooler and provides a dyno-proven 13-degree average reduction in oil temps. This kit also adds 0.76 quarts of oil to the system, so you can stay on the throttle longer without driving up your oil temps. We've included pre-assembled black nylon-sheathed -10AN braided stainless-steel lines to make installation easy and provide ample flow to critical engine components. The Mishimoto GR Corolla performance oil cooler kit is available with a thermostatic oil filter sandwich plate for daily drivers or cold climates, or with a non-thermostatic sandwich plate for dedicated track cars or those in hot environments. Like all Mishimoto products, this oil cooler kit is backed by our Mishimoto Lifetime Warranty so you can pin the throttle with confidence knowing we have your GR Corolla's back.
