CSF 8178 Charge Cooling Upgrade for BMW F90 F91 F92 F93 M Models

Take control of intake temps and keep power consistent with the CSF 8178 high performance charge cooling set for the F9x BMW M cars. Designed for the S63 twin turbo V8, these air to water heat exchangers stabilise IAT, resist heat soak on hard road use and track days, and deliver reliable performance on tuned or stock setups. Perfect for enthusiasts chasing stronger back to back pulls, improved 60 to 130 mph times and dependable thermal management on fast road and circuit work.

At MJ Modifications we have fitted this CSF kit multiple times and the results speak for themselves. Customers report noticeably cooler charge temps, quicker recovery between runs and better repeatability when tuned. The package installs cleanly with factory style connections and looks superb in the bay.
