Oiled wire-mesh air filters came standard on almost all vehicles back when some of us were just getting into cars so it isn't something that the car manufacturers don't know about. There must be a reason why they no longer use them and the over-oiling problem could be part of it. My personal experience with K&N was when I put one on a 92 Chevy pickup along with a cat-back exhaust and a couple of other minor changes. I felt that the truck ran stronger but it could be that it was just louder. I certainly didn't have it tested.

One thing that caught my eye while reading the fine print in a K&N printed advertisement shortly after (no internet back then) was that some of the tests that showed K&N filters to be far superior to paper were done on filters with 50,000mi on them. All that really told me was that paper stops up quicker. Paper may be just as good if changed at specified intervals but, like the egg in the cake mix, I felt good about having the K&N.
