CSF 2014+ BMW M3/M4 (F8X) Front Mount Heat Exchanger w/Rock Guard

The CSF Front Mount Heat Exchanger w/ Rock Guard for the 2014+ BMW M3/M4 (F8X) is the ideal first step in solving the heat soak issues that plague the S55 platform. Even without upgrading the charge-air-cooler, adding this heat exchanger delivers noticeable reductions in intake temperatures, helping maintain consistent power on the street or at the track.

Designed as a true drop-in fit, this heat exchanger requires no modifications and accepts all OEM components — including quick-connect hoses, brackets, the X-brace, and all factory shrouding. Available in a polished finish (CSF #8075) or a stealthy satin black (CSF #8075V) for an OEM+ look, it comes complete with a durable rock guard for added protection during spirited driving or track use. If you're planning to upgrade your S55 cooling system, this is the best place to start.
