Product Information

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.

Fit like it should

Got this for a vehicle I have been working on. There was nothing flashy about it; it just looked like a well-made replacement. Happy to have the repair finished. The hardest part was getting access to the old component.

Good experience overall

I ordered it for a weekend project. I inspected the edges and connections before installation and did not see any issues. So far, I am happy with the purchase.
