Mishimoto 15-20 BMW F80 M3/M4 Oil Cooler Kit

When you're pushing your BMW M3 or M4 hard, keeping oil temperatures in check is crucial for engine health. The factory oil cooler, while cleverly placed to use airflow, is vulnerable to road debris and can be a weak point under demanding conditions. This Mishimoto oil cooler kit is designed to give your S55 engine a much more robust cooling solution.

This kit replaces the stock tube-and-fin cooler with a full aluminum, TIG-welded bar-and-plate unit. This construction is inherently stronger and offers improved heat transfer, helping to better manage oil temperatures during spirited driving or track use. Mishimoto has increased the core thickness by 10mm, resulting in a 46-percent larger core volume and an additional 0.4 quarts of oil capacity. To further enhance durability, the kit includes flexible, nylon-braided oil lines that replace the factory hardlines, which are more susceptible to abrasion and corrosion damage. Specially designed adapters are included to connect to the S55's oil pump and the new cooler.

This Mishimoto oil cooler kit is designed as a direct fit replacement for the stock unit, simplifying installation. It comes with all necessary adapters and lines for a complete system upgrade. The kit is backed by the Mishimoto Lifetime Warranty, offering peace of mind for your investment.
