Very important to read the instructions. The bolts are not to be more than hand tight. When tightening, it is not recommended to use a tool or all your strength as the bolts both snapped with base left inside, had to reorder replacement bolts and they were not cheap:(
I installed this in less than 20 minutes on my 2015 street Bob. It was pretty straight forward and simple. Hand tight is all you need to tighten everything involved with this. It only calls for 5lbs. It looks great, it's one of the best bang-for-buck air cleaners out there. I recommend this product. Also, I'm not very interested in working on stuff or turning wrenches and I was able to install this with no problems, so I think anyone could install this.
