They finally did it. Not sure where you can get one yet, but they have introduced a K&N air filter for the Brute Force. The K&N part number is: KA-7504!!!
If anyone finds out who's selling them let me know!!!
Here's a link!

I thought K&N's let too much dust into the intake and were generally frowned upon.

 

Wow, never really heard of that one. I have and have had K&Ns on nearly all of the vehicles I've owned and they've aways been nice and clean inside even in the dustiest of conditions.
You do have to wash them and oil them properly as per the instructions occasionally and I have seen others on the forums ave trouble with them because they don't do that.
They definietly increase flow, they tend to repel water much better than most (especially with the Gore-tex outerwear cover), and they last forever with practical and common sense care and feeding. What more can you ask for?

 

EVERY K&N filter that I have ever used has passed some degree of fine dirt. And I am a fanatic about cleaning and oiling them. I refuse to use them anymore on either my quads or my vehicles, and I really wanted to believe they were the best. Oiled foam for me. (I have a major problem with ANY filter that I can see clear daylight through...it doesn't take an expert to know what's going to happen) Just my experience, and my .02 worth.
