The CSF High-Performance Power Steering Cooler keeps power-steering fluid temperatures in check on the BMW E9X M3 driven hard on street or track, preventing the fluid boiling that causes sloppy steering and a noisy pump. It changes from the OEM low-efficiency mechanically bonded core to a CAB-brazed high-efficiency plate-type design using AC Condenser Technology with a 1-row super-high-pressure 18mm 4-channel microtube. The dual-pass 6-row design adds 83% more surface area for roughly 40% greater efficiency, and its increased height (83mm/3.27in) clears aftermarket superchargers and auxiliary coolers. Drop-in fit with OEM connections. Replaces OEM part number 17112282716.
