Does anyone have anything good or bad to say about washable air filters? I am considering buying a K&N Air Filter and the idea of being able to re-use the filter rather than dropping $15 each time is pretty compelling! I searched the google groups for answer but there is a lot of conflicting information, the KN web site of course offers glowing indorsements. Is it correct that I have to also buy a "cleaning" kit from the company to clean the little bugger?
Anyone have any experience with these filters?
Thanks!
