The Mishimoto Performance Oil Cooler Kit adds durability and cooling capacity to the 2015-2020 BMW F8X M3, M4, and M2 Competition. The factory tube-and-fin cooler hangs perpendicular to the cooling stack, exposing it to road hazards. Mishimoto replaces it with a full-aluminum TIG-welded bar-and-plate cooler that adds 10mm of core thickness for a 46 percent increase in core volume and raises oil capacity by roughly 0.4 qt. The kit includes flexible nylon braided lines, an oil line fitting kit, and adapters for AN fittings off the S55 oil pump. Backed by the Mishimoto Lifetime Warranty.
