BAMCO M8 Bagger Oil Cooler

The M8 Touring Oil Cooler is engineered to deliver superior temperature control and performance for your Milwaukee-Eight engine. Designed to work with the factory Harley-Davidson “Chopped” Engine Guard or aftermarket crash bars, this system enhances your bike’s cooling efficiency—perfect for city riding, traffic, or extended trips.

Unlike stock oil coolers that struggle to manage heat, this side-mount UltraCool system works alongside the factory cooler to lower oil temperatures more effectively. Combined with a FLO Oil Filter, it provides performance comparable to a fully liquid-cooled engine. Built for durability and ease of installation, this kit includes a powerful dual-fan setup, automatic thermal switch, waterproof wiring, and premium stainless-steel braided lines.
