Mishimoto Performance Oil Cooler - BMW M5 M6 M8 M850i 2012-2025

The Mishimoto Performance Oil Cooler keeps the S63 twin-turbo V8 in check on the BMW M5, M6, M8, and M850i, addressing elevated oil temperatures seen during track driving. CNC-machined billet-aluminum end tanks are TIG-welded to a robust bar-and-plate core; the 55mm-thick core delivers a 24 percent increase in core volume and a 40 percent increase in external fin surface area for greater heat transfer. This complete bolt-on includes mounting hardware and replacement O-rings for the oil lines, and is finished in durable silver powder coat. Backed by the Mishimoto Lifetime Warranty.
