CSF 2015+ BMW M3/M4 (F8X) DCT Oil Cooler

Direct replacement for the factory DCT cooler with a dual-pass layout for longer exposure to cooling air. It reduces the potential for temperature-related faults and limp mode during track events. The dual-pass design achieves increased surface area within the original dimensions. Made with CSF’s AC condenser technology using a 1-row super-high pressure 26mm multi-channel microtube. Features a dual-pass high-performance core with 12 cooling tubes vs. OEM single-pass with 6 tube design. Lab tested at approximately 30% more efficient than the OEM cooler. High-density multi-louvered fin design. Drop-in fit requiring no modifications to install. Accepts all attaching OEM components including oil-line connections, mounting brackets, and shroud/ducting. It is the world’s 1st and only true plug-and-play upgraded DCT transmission cooler for F8X.
