You can get K&N or Uni filters, I went with the Foam Uni and outerwear because I am looking for filtering and the K&N just doesn't cut it in this Arizona dust in my opinion.
I got the optional Super Seal that goes around where the stock air filter would be so the lid will still seal but I'm not so sure I would recommend it. It is now laying in the dirt next to my garage since after the first ride it was mishaped and sucked into the airbox from the vacuum. It might be because I installed it with grease when it probably would have worked dry but my reason for the whole intake mod was due to the factory setup sucking in dirt so I was trying to seal it the best I could.
]]>I went with the dual stage Uni filters with an Outerwear. It comes with a
crankcase breather filter in case you want to run with the lid off. I'm going to
keep my lid on but I installed the filter anyway. It was pretty easy to install
the hardest part was getting the stock plastic velocity stacks out of the
airbox, SERIOUSLY! What a PITA! The new billet ones went in great and the
filters clamp on very securely do to the ribbed clamping surface. (Stock plastic velocity stacks vs. new billet ones) I also got Albas' airbox lid seal (a little different than the other guys)
so the lid will still "hopefully" seal with no stock filter in place which wouldn't
matter since no dirt will get by the clamped on filters. A quick test drive
resulted in nothing actually. Obviously no change in power but I thought the
intake noise would be a little louder but it's not.
