Oil Cooler Fan 2017-2023 Touring® Models

The ThunderMax Oil Cooler Fan for 2017-2023 oil cooled Touring®* models is the answer to overheating M8 engines. The fan only takes 15 minutes to install and is plug-n-play. If your motorcycle is equipped with a ThunderMax ECM, just plug the fan in and you are ready to go. If your motorcycle has a stock ECM you will need to visit your local dealer to have the bike flashed.

The oil cooler fan works by using engine temp and vehicle speed to reduce heat and keep your M8 engine running cool.
