CSF Race-Spec Engine Oil Cooler - BMW M3 E9X 2008-2013

The CSF Race-Spec Engine Oil Cooler keeps engine oil temperatures down on the BMW E9X M3 driven hard on street or track, helping avoid the limp mode that high oil temps trigger in modern cars. It uses a dual-pass high-performance core with 10 cooling tubes (vs the OEM single-pass 6-tube design) and CSF's AC Condenser Technology with a 1-row super-high-pressure 26mm multi-channel microtube. Lab tested at approximately 30% more efficient than OEM, it is a drop-in fit accepting all OEM oil-line connections, brackets, and ducting. Replaces OEM part number 17212284075.
