On my 60th Birthday, I have been blessed with a 2005 HD Electra Glide Ultra Classic with a stock Twin Cam 88. While upgrading the Cam Chain Tensioners, I chose to install the Ultra Cool Oil Cooler. The install instructions that came with it, as well as the web videos I found made for a clean install. I had to custom fit the regulator/cooler mount, but the instructions gave me a heads-up on that as well. I just finished my first test ride, and it works excellent. I was happy to find an American Made product. I can’t wait to ride with my brothers and say good things about you and your products. God bless, Chap Devon
