Description
The Mishimoto MMOC-GRC-23NTSL is a purpose-built performance oil cooler kit engineered specifically for the 2023+ Toyota GR Corolla and its high-revving G16E-GTS 1.6L turbocharged three-cylinder. This particular kit ships with the non-thermostatic silver cooler option, built for dedicated track cars or owners running their GR Corolla hard in hot climates. At the heart of the kit sits a 14-row dual-pass bar-and-plate oil cooler finished in anodized silver, paired with pre-assembled -10AN nylon-sheathed braided stainless-steel lines for a clean, durable installation.
Toyota’s Gazoo Racing engineers packed serious output into a small-displacement engine, and with a 10.5:1 compression ratio and a fast-spinning turbo working overtime, oil temperatures on the GR Corolla can climb well past 260 degrees under hard use. This Mishimoto oil cooler kit addresses that head-on: the 14-row dual-pass core mounts in the upper grille using direct-fit brackets to maximize airflow, and the added 0.76 quarts of oil capacity helps the system absorb heat more effectively. Selling points reported for this kit include an average reduction in oil temperatures of 13 degrees, giving drivers more confidence to stay on the throttle without watching the oil temp gauge climb. Anti-vibration mounting grommets protect the cooler over rough roads, and the bar-and-plate construction is built to handle both street and track duty.
Vehicle Applications
This Mishimoto oil cooler kit is a direct fit for the Toyota GR Corolla built from 2023 through 2025, equipped with the G16E-GTS engine on the GZEA14 chassis. No other vehicles are covered by this kit.
