The F97 X3M and F98 X4M are powered by the same S58 engine found in the G8X M3, M4, and M2. These SUVs are capable of massive power and incredible speeds. However, they stuffer from the same heat issues as their Sedan and Coupe cousins. CSF's Cooling Systems have become core upgrades for S58 owners, even ones keeping the engine mostly stock.

Many owners have been upgrading their X3Ms and X4Ms with the CSF "Level Up" Charge Air Cooler Manifold for years now. The fastest examples are all running the CSF Manifold and have been asking for more cooling upgrades. After over a year of development and testing, CSF is pleased to offer the Front Mount Heat Exchanger & Transmission Cooler Module for the F9X X3M / X4M.
