whats the best

The best is the one that is easiest for you to maintain. This is a personal preferance question. I like foam filters because I think they are easier to maintain and work better in heavy dust, mud and water than K & N. Although I have never owned a K & N, i do know they take a little more care to get the most out of them.
I think the guys that ride mostly in sand tend to like the K & N more than foam.

 

Most guys that ride sand use foam filters to keep the fine sand out.

 

i run a K&N w/ outerwear filters and i ride in realli dusty arear and have not have a problem yet

 

yea the K&N is great in conditions... i ride in dusty stuff and in the wet stuff and never found a problem with anythin gettin through, i would use the outerwear for added protection tho

 

when i get my YYZ i was thinkin about the curtis sparks air super charger you might look into it

 

I am racing a series and it is kind of dusty. And when I service my quad I notice that there is some dust getting by my K&N filter , so ordered some foam filters for the pro flo kit, and yes I was using an outerwear on my K&N, and I will still run it in the sand dunes here in Oregon, but for dust it is going to be foam for me!

 

Foam filters, I run a UNI.

 

the best air filter for what? if it is power the best is none at all. If it is anything else i have had no troubles with my k&n with prefilter

 

UNI. Gave me more power and leaned me just right. From the factory I was running rich and installing the UNI in place of my stock foam filter was a no-brainer.
