It looks like a little air cleaner. I think it looks nicer than the stock cow bell that most Harleys have. I also installed the Arlen Ness Big Sucker Derby Cover air cleaner. I like the symmetry of having 1 point cover and 1 derby cover on each side of the bike.
I was able to install the Arlen Ness Chrome Horn Cover in less than 10 minutes. The chrome finish is great. Arlen Ness made this horn cover out of thick, heavy gauge steel and then chromed it. The only thing I would like to see different is to have the entire horn cover sit a little higher towards the tank and not so low. You use the original mounting hardware which causes the cover to sit low. I would recommend this product to a friend for sure.
