What's everybody running?

 

Just the stock foam filter.
I'm thinking about a K&N. Is it worth it?

 

You will get much better filtration with a Uni-Filter. K&Ns are fine in moderately dusty conditions. But when the dust is really flying, your best bet is a Uni.

 

I use my stock filter and a Uni air filter on my Raptor and I can't tell any difference. Maybe after some time goes on one will hold up better than the other. I use to clean my filters PJ1 foam filter cleaner spray and follow directions on the can. Since I have two filters I can now slap the other one on without having to wait for it to dry. For the oil part of this question I use PJ1 foam filter treatment spray (super tacky). When I look down the airtrack with either filter off it always looks clean. Chet
