BAMCO M8 Softail Oil Coolers

The M8 Softail Oil Cooler is designed to keep your Milwaukee-Eight engine running cooler and performing at its best. Built to work alongside the stock oil cooler, this system dramatically improves oil temperature control—especially in traffic or during long rides. Engineered for maximum efficiency, the UltraCool Oil Cooler delivers consistent cooling performance that rivals a fully liquid-cooled setup when paired with a FLO Oil Filter.

With dual waterproof fans, a precision aluminum heat exchanger, and plug-and-play installation, this cooler is built for reliability and simplicity. The 3.0 version features a thermal switch that automatically activates for optimal temperature management.
