The egr dumps raw exhaust into the intake, in the case of diesels, it dumps particulate - far more then you ever see out the tailpipe - into the intake between the filter and the turbo. Most of the particulate is burned off in the cat, and what is left is out the tailpipe. All stock diesels in the last 10 years or so have a egr from the factory. Gas engines have had one sense the late 70's, but the exhaust is far lower in particulate then diesels.
My point is the extra dirt that the k%n and similar filters let in isn't alone, from the factory there is a lot already there.
