CSF high-performance engine oil cooler for the BMW M5, M6, M8 and M850i (F1X and F9X chassis, S63 V8). The factory all-metal cooler has several weak points; CSF reinforces them with a rugged bar-and-plate core, cast end tanks and 100% TIG-welded construction. Developed alongside CarBahn Autoworks to handle the heat of their S63 stroker kit, it installs drop-in with CNC-machined brackets and OEM-style inlet/outlet connections (trimming the OE ducting and lower radiator cradle is recommended for best fit). Every unit is individually leak and pressure tested.

Looks well made

Bought this while sorting out a few things under the hood. The job was not especially fun, but the component itself did not add any headaches. So far, I am happy with the purchase. I did the work myself.

Fit was right

I bought this after looking at the dimensions and application notes. I had to work around some tight spaces, but that was more about the vehicle than the part. Overall a good experience.
