When I ran a K&N, I would routinely find dust, in the air tube, downstream of the filter. I have a picture of it on my web site. If you don't have dust where you live, its probably not much of an issue.....many folks do have dust.

stop as much? no

store as much? yes

they will actually trap more before becoming clogged, due to the pleated design...but they will also let more particles by in the process...

I had one in my TJ and the answer is no. I ran and AFE Stage two pod in my 7.3 L super duty diesel and that didn't stop the dust either. I am now running a stock filter in my tj and the ford AIS system. less air flow but better protection

The real question comes down to what paper filter you are using to compare it to... Some filters out there are total junk. Also, the seal between the filter and the air box is just as important as the filter media. It is actually ideal to apply grease around the filter lip to aid in the seal to the airbox.

So, regarding if a K&N filters better than an OEM filter, it most likely will not. Another thing to consider though is if it filters "good enough". I do have dusty conditions here however through used oil analysis I have never had high silica levels using my Airaid cone filter on my Airaid intake pipe. With that said, I will be changing to an AMSOIL AaO cone filter before too long to see if I get lower silica levels.
