If we're talking ability to filter the crap out, i won't touch K&N with a barge pole these days.

Yes they do breathe more than most filters, however, they filter fairly poorly. When i start seeing the cotton material turning up in UOA's, then stop to think for a second what the path would be to get there, i figure i'd like *some* filtering on my engine.

I don't like wet type filters anyway, dry has a lot more benefits and consistency than oiled types.

BTW, paper is the medium used to see what passes through all these performance filters, you should be using the factory/paper medium filters as a benchmark for filtration ability.

My next filter will likely be an Apexi drop in filter if not the factory fit.
