Installed the Ultracool on my 2002 FXSTBI and I’m seeing a drop of around 20-25 degrees. Would recommend, No leaks or issues and its performed great. The install was a few hours but I wanted to take my time and make sure everything was torqued and leak free. The tubing wrench socket they provide is a lifesaver!
