The Mishimoto Performance Oil Cooler upgrades the vulnerable factory oil cooler on the 2021+ BMW G8X M2, M3, and M4. The stock unit sits on the undercarriage parallel to the road, exposing it to scrapes and debris. Mishimoto replaces the factory tube-and-fin cooler with a bar-and-plate unit featuring CNC-machined end tanks, a 35.7 percent thicker core, and a 41 percent increase in core volume for superior cooling. It fits directly in place of the stock cooler and retains the factory seals and bash guards. Full-aluminum TIG-welded construction. Backed by the Mishimoto Lifetime Warranty.
