Engineered for 2017-current FLH Milwaukee 8 frames equipped with HD "Chopped" Engine Guards or similar height aftermarket crash bars, this side-mount oil cooler installs on the down tube without requiring modifications. The "Naked" design, which omits external covers and grills, is specifically sized to fit perfectly inside an M8 CVO Road Glide fairing spoiler. At the core of the system is a specially designed dual-pass aluminum heat exchanger featuring turbulators to maximize heat dissipation, ensuring optimal oil temperatures are maintained between 200 and 230 degrees.
The cooling system utilizes sealed waterproof IP68 dual fans that generate 220 CFM of airflow, automatically activating via a thermal switch with waterproof connectors when oil reaches 210 degrees and remaining on until temperatures drop to 185 degrees. Installation is streamlined through a plug-and-play wiring harness with a relay that connects directly to the battery under the seat, while black nylon-coated stainless steel braided oil lines with AN6 fittings provide secure fluid transfer. An LED indicator light on a black perch mount confirms fan operation, and the package includes a special oil line fitting wrench along with detailed instructions for setup.
