Description
The Mishimoto Oil Cooler Kit (MMOC-MUS8-18T) brings a purpose-built, bar-and-plate oil cooler to the S-550 chassis, engineered specifically for the 2018-2023 Ford Mustang GT’s 5.0 Coyote III V8. Mounted directly in the upper grille for maximum airflow, it’s the largest oil cooler Mishimoto offers, paired with an application-specific mounting bracket that doubles as an air diversion panel to funnel even more cooling air across the core.
Built around a Performance-grade, anodized Silver bar-and-plate core, this Mishimoto oil cooler kit is designed to keep engine oil temperatures in check without stealing airflow from other cooling components — its compact upper-grille mounting position leaves room for supercharger heat exchangers on modified Mustangs. The kit ships with pre-made stainless-steel braided lines terminated in durable -10AN fittings for a clean, leak-resistant installation, along with a billet aluminum thermostatic oil sandwich plate that helps protect against overcooling by regulating oil flow through the cooler. Because it replaces the factory fluid-based oil cooler, the kit also includes a replacement lower radiator hose, reducing load on the engine’s cooling system while increasing overall oil capacity by roughly 1 quart. Every Mishimoto cooler in this kit is backed by the Mishimoto Lifetime Warranty.
