Dredging up some of my old posts, and saw this one. Thought I'd add, for my own vehicle, I have two filters. I clean and oil one in a very slow process while it's off of the vehicle, and then swap when needed. I've found the best thing is to let the filter dry naturally and completely. Then when oiling, go sparingly, and let it wick in naturally. If the filter is damp, the oil doesn't want to wick, and in order to get it everywhere, you end up over oiling. And that ends up on the airflow sensor, and that's no good. My intake tubing and MAF are cleaner than many vehicles I run across using the stock filter set up, and I like it that way.

Of course, this does no good for the situation I originally faced, those are still problematic, but it works well for my personal vehicle.
