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.
