Mishimoto Performance Heat Exchanger - BMW M2/M3/M4 (G80/G82/G83)
Mishimoto has re-engineered the factory heat exchanger for the BMW M2/M3/M4 from the ground up, ditching the plastic end tanks for a fully aluminium, TIG-welded construction built to handle sustained track abuse. It's designed as a bolt-on upgrade to the air-to-water intercooling system, giving your charge air a genuine boost in cooling capacity without touching factory tuning or piping.
This listing covers the BMW M2, M3, and M4 (G80/G82/G83), suiting both automatic and manual gearboxes. Select your correct transmission variant (SKU MMHE-G80-21AT for automatic, MMHE-G80-21MT for manual) from the options on this listing before ordering.
Note: Installation requires removal of the passenger side factory rock guard tab. Refer to step 11 of the Mishimoto installation guide for details. Listed install difficulty is rated 3 out of 5.
