The CSF DCT Transmission Oil Cooler is a true plug-and-play upgrade for the S55-powered BMW F80 M3, F82/F83 M4, and F87 M2 Competition, installing in the OEM location with no modifications. 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 the OEM cooler. Replaces OEM part number 17112284503.
