The CSF cooling module is a high-performance upgrade for the BMW F97 X3 M and F98 X4 M (S58), combining an upgraded heat exchanger and a dedicated transmission oil cooler in a single integrated unit. The 2-row 42mm core dramatically increases cooling capacity over the OE setup, holding both coolant and transmission temperatures down during track use and high-load driving. Direct-fit to the factory location.
