Compatible Models: This UltraCool Oil Cooler 3.0 kit is designed for use on all 2017-2025 M8 Oil-Cooled Cylinderhead Touring Models with a Harley “Chopped” Engine Guard or similar height aftermarket crash bars. It does not fit the 2023.5 CVO Road Glide or the 2024-2025 Touring Models with liquid-cooled cylinder heads. The UltraCool Oil Cooler for these models will be available in June 2025.
Why You Need the UltraCool Oil Cooler 3.0: M8 engines are equipped with oil coolers that circulate oil to the heads, but the stock cooler often isn’t sufficient to prevent overheating in traffic or city riding. Unlike traditional oil coolers, our Side Mount UltraCool Oil Cooler 3.0 works with the stock cooler, cooling all of the oil to keep your engine running at optimal temperatures. With the addition of a FLO Oil Filter, this system can provide your M8 engine with the performance equivalent of a FULLY liquid-cooled engine!
