The Mishimoto air-to-water intercooler for 2015–2020 BMW F8X M3, M4, and M2 Competition upgrades cooling with full cast-aluminum end tanks TIG-welded to a bar-and-plate core. Enlarged core volume and a single-pass fin layout improve heat transfer, increasing flow and lowering intake temperatures in testing. The intercooler installs without modification, offers notable cooling gains, and is backed by Mishimoto's Lifetime Warranty.
