Many of you probably already know. But I just replaced my 2013 air cleaner assembly with a take off 2014 unit. It's a direct fit. My Harley dealer already had a take off. I like the looks of the 2014 unit. The tried and true oval is kind of outdated in my opinion. I had my 2013 Tri-Glide in the dealership to fix the air suspension bleed off i was experiencing. Got that fixed and they slapped the air cleaner unit on for me. Thought I would pass that little bit of info on.pepper
