BMW M4 Charge Cooler Upgrade DIY (2015-2021 BMW F82 M4, F80 M3, F87 M2 Competition, M2 CS)

The BMW S55's air-to-water intercooler, also called a charge cooler, is a neatly packaged way of cooling the air pressurized by the turbochargers. However, the OE unit is known to leak internally, so replacing or upgrading the charge cooler is a must for many. The aftermarket is full of solutions for this issue, and no matter the brand, they'll feature a more robust construction and a large core to better handle extra power.

CSF is one of the most respected names in the cooling game, and their S55 charge cooler is a safe choice. Their quality and proprietary designs make them one of our go-to's, and this specific cooler's performance on upgraded S55 engines speaks for itself. Pair this with CSF's improved auxiliary radiator for the ultimate intercooler setup for your F8X M4, M3, and M2.
