BMW M3 Oil Cooler Kit - Mishimoto - Performance Oil Cooler - Silver - `15-`20 is a direct-fit upgrade for 2015–2020 F8X M3/M4 models. This kit replaces the stock cooler with a stronger, higher-capacity unit intended to improve oil cooling and durability on street and track cars.

The Mishimoto unit uses a full aluminum, TIG-welded bar-and-plate core instead of the factory tube-and-fin design. The core is 10mm thicker, yielding a 46% increase in core volume and about 0.4 qt additional oil capacity. Mishimoto supplies application-specific nylon-braided oil lines to replace the factory hardlines, plus specially designed adapters to accept AN fittings at the S55 oil pump and to mate cleanly to the cooler. The kit fits in the factory location, offers a more robust heat exchanger construction to resist road debris, and includes Mishimoto’s Lifetime Warranty.
