Looking to get rid of the stock air cleaner on my Blackline and im looking at the arlen ness big sucker. Question is, whats the difference between the stage I and stage II? Bout the same price point.
Anyone have any opinions?
thanks

 

Stage II has a 20% larger surface area on the filter element. The Stage I tapers from big to small, back to front. the Stage II tapers from small to big, back to front if looking at it as if you were looking into the throat of the throttle body. Go for the Stage II, it doesn't look so wimpy on the side of the bike...

 

thanks, that's what I thought. was lookin at them and saw the tapered. ill order the stage II
