I installed my Ultra Cool oil cooler on my 2012 Wide Glide. Just the cooler itself made a difference. I tried to get my bike hot enough to kick the fans on but couldn’t get it hot enough that day. The one thing is I have an engine guard on my scoot and had to drill 2 holes about an inch up for the cooler to fit. Didn’t want to lose my engine guard and drilling two holes was easy enough. Did have a minor leak at the fitting which had to pull the oil filter to get to it but once again no biggie and all is good now. Can’t wait till the weekend when I can Finally get out and Ride and see if I can get the fans to come on..All and all very happy with this product
