However, I'd rather spend $ on replacing (vacuuming out my stock filters works for a few times) my factory filters than see black oil every 3-4k miles because my K&N's letting in too much dirt.
I see a noticable difference in oil color on my 911 turbo between the k&N & the OEM Mahle paper filter. Noticeable. That might be somewhat irrelevant, but still, peace of mind to know the factory pulls more dirt/dust.

So you think oil gets black from dust getting past the rings? Really? Come on. You might want to check that restrictor on the turbo oil inlet.
