Great air intake and looks beautiful on the bike. It is not as big as the stock harley 103 air cleaner. Don't lose the o-rings, and buy a fuel pack so you can update your fuel settings. I purchased a Vance & Hines FP3 it paired up great.
Installed in less than 1/2 hour. Looks way better than stock. I have a 2012 Road King with 114k miles and cleaned the stock filter religiously. All I can say is WOW. Can't wait to see what else happens.
