Better yet, "SonOfSwede" <img src="/forums/images/graemlins/wink.gif" alt="" />

I was always under the impresion that as a K&N got dirtier, it would filter more effeciently but also lower it's initial performance gain (the reason you buy it is for better air flow I assume). I have a K&N just because I won't have to buy another air filter again, I just usually clean it in the fall and sometimes on really dusty trail days, I'll beat some of the dust out of it.

so anyway, as the K&N gets dirtier, doesn't it filter better? (same thing for the green I think?) As opposed to standard filters that just get worse and much less efficient with time and then need to be thrown away.
