Mishimoto Performance Oil Cooler - BMW M2 M3 M4 X3M X4M F8X 2015+

The Mishimoto Performance Oil Cooler upgrades the factory tube-and-fin cooler on the 2015+ BMW F8X M3, M4, M2 Competition, and X3 M / X4 M. The stock cooler hangs perpendicular to the cooling stack and is exposed to road debris. Mishimoto replaces it with a full-aluminum TIG-welded bar-and-plate core that adds 10mm of thickness for a 46 percent increase in core volume and raises oil capacity by 0.44 qt. It fits directly in place of the stock unit. Backed by the Mishimoto Lifetime Warranty.
