It looks at its best on any bobbed or chopped bike. It’s slightly smaller than the traditional Goodson air cleaner (6 1/2″ x 3.5″), ribbed to emphasize the retro style,  breathing big through its Unifilter element.  Of course, I use it on my custom bikes (see it on my Peacemaker Chop featured in current issue of Easyriders, or in my website).  I have a few left in stock for S&S carburetors  (drill yourself the 3 holes in the backplate if you have a CV carb).  Dont miss this one or you are going to regret.
