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

The CSF Front Mount Heat Exchanger w/ Rock Guard for the 2014+ BMW M3/M4 (F8X) is one of the most effective first steps to combat the heat soak issues common with the S55 engine. While pairing it with a charge-air cooler is the ideal full upgrade, even installing just the heat exchanger significantly improves the system’s ability to shed heat — the biggest weak point in the factory cooling setup.

This heat exchanger is a true drop-in fit, requiring no modifications and designed to work seamlessly with all factory components, including quick-connect hoses, mounting brackets, the OEM X-brace, and all factory air ducting. It comes with an integrated rock guard for added protection and is available in a polished finish (CSF #8075) or a stealthy satin black option (CSF #8075V) for an OEM+ look. If you're starting your S55 cooling upgrades, this is where you should begin.
