See, this is where throwing a pinch of salt in a freshwater lake turns it into saltwater; there's no sign of units anywhere.
Not all of the dirt that makes it to your airbox gets to the throttle body - you've got a filter for that. So some tiny amount of some other tiny amount gets by and into your oil if it doesn't get incinerated and shot out the exhaust first, finding its way into the filter and then maybe out.
If a car tends to find its way into dusty rallycross stages or dirt roads, I could see this being a bit more of a concern. For the casual city car? Probably about as much of an issue as throwing that pinch of salt in a lake and noticing by taking a drink.
I don't use a K&N, but I'll feel free to defend it only as it's unduly discredited by empty words like "more" and "worse".
