I agree that the bolts are a PITA for sure but it is a nice cooler. If mine ever goes I will replace with a JAG Side mount.deucedog said:I installed the Super Premium oil filter on my Ultra and it's been fine so far, no leaks or problems. The biggest issue is when the bike is stopped or going slow in hot weather, the oil cooler isn't going to help you too much except buy you additional time. The bike simply starts to heat up from a lower temp when you have a cooler.
Took me about 4 hours to do the job and it's pretty difficult to get to all of the bolts, but I managed. If you don't have a good selection of tools, let the dealer install it for you.
I think it's a worthwhile addition if you buy it from Hales or one of the other online discounters.
