BMW M4 Oil Cooler Kit - Mishimoto - Performance Oil Cooler - Silver - 2015–2020. A direct-fit upgrade for F80/F82 M3/M4 owners, this Mishimoto oil cooler replaces the stock tube-and-fin unit with a stronger bar-and-plate design to improve durability and oil cooling capacity.

This kit uses full-aluminum, TIG-welded construction to provide a more robust heat exchanger in the vulnerable front cooling stack location. The core is 10 mm thicker than stock, yielding a 46% increase in core volume and an additional 0.4 qt of oil capacity. Mishimoto supplies application-specific nylon-braided oil lines and specially designed adaptors for AN fittings to connect to the S55 oil pump, addressing abrasion and corrosion-prone factory hardlines. The kit fits directly in place of the OEM cooler, includes the necessary oil line fitting hardware, and is covered by the Mishimoto Lifetime Warranty for long-term peace of mind.
