This unit was installed on a 2014 HD Street Glide, we know the difference between a well built product and not so great, UltraCool got it right. The install was straight forward, if you have any questions like I did all you have to do is call or drop a Email they bent over backwards to help and answer any (11:00)question. After the install the bike was road tested I kept the RPM’s up to see what this unit was going to do over the OEM cooler, when I got back to the shop we took some heat readings. Bottom line is it works. just dam happy. I would also like to say the unit looks great the fit and finish are well done, I hope to install more. Ride hard, Take care
