The thing that always puzzled me, is how my used K&N's were ALWAYS SO CLEAN! Was it because the Outerwears did such a good job that the filter had nothing to do, or was it that the filter wasn't catching the stuff? It just always bothered me.

If it was the Outerwears catching everything, well now I have the best of both worlds! I have an Outerwears on my airbox lid (http://www.ehsracing.com/), and the security of a good flowing UNI foam filter on my carb. Now, I'm a much happier rider!
