Mishimoto G8X G80 M3 G82 M4 Oil Cooler (2021 - Present)

Upgrade the cooling performance of your 2021+ BMW G80 M3 or G82 M4 with this Mishimoto Performance Oil Cooler. Designed for the G8X platform, this upgraded oil cooler helps support consistent oil temperatures during spirited driving, track use, and demanding performance conditions.

The factory oil cooler is positioned for strong airflow but can be vulnerable to road hazards due to its location. Mishimoto improves on the OEM design with a durable bar-and-plate construction, CNC-machined end tanks, and increased core capacity for improved cooling efficiency.

This oil cooler is designed as a direct replacement for the stock unit and retains the original seals and bash guards. With a 35.7% thicker core, 41% more core volume, and Mishimoto’s Lifetime Warranty, it is a strong supporting upgrade for performance-focused G8X M3 and M4 builds.
