Just looking for an opinion between a couple of air cleaner kits I'm eyeballing. I have ordered a Arlen Ness Big Sucker Derby but I keep going back to the S&S mini teardrop stealth. I really like the looks of the stealth but I kind of like the idea of the Derby and being able to swap out with different derby covers for a different look from time to time. I know looks are a matter of opinion so I'm mainly wondering if there is any performance differences between the two.

 

Not really, they will only flow as much as the bike will allow.. Your bike won't know the difference

 

Your intake is going to determine the rate/performance. Any air cleaner claiming to flow more/better volume over the competition is bunk. That's why you don't need a tune when you swap them over, ditto for your pipes. For example I was sick of my knee whacking the HD football, took it off and popped a trim cover on and ride with a naked look. Nominal comfort change for my knee but I do like to look.

 

Most aftermarket air cleaners flow more air then a Harley engine can use.
Now it's up to what looks good to you, get the one you like the looks of.
