Perfectlap,

Did you read what you wrote? Let me quote you;"The problem was that whenever I removed the filter (K&N) to clean it, the thing was just filthy. the sink in my garage was full of grit, sand and all manner of debris." Then in the same breath,"I'm not really sure what it was filtering!"

Let me tell you what it was filtering...GRIT, SAND and ALL MATTER OF DEBRIS!!

Was your paper filter that dirty when you replaced it? No? Then you should ask yourself,"I'm not really sure what it was filtering!"

Air flowing through a tacky oil impregnated cotton media will catch more dirt than a dry paper filter. If the dirt is caught in the paper the draw of air can work it through. Once dirt is caught in oil its there to stay until the break down solution is used to clean the filter.

P.S. If you had that much crap in your filter you might want to check it more often.
