I consider the use of oiled foam filters a total waste of money and a harmful product.

In no way what I am about to say is condoning the use of K&N filters as I do not use them. I've read the independent tests and will not use K&N on any of my vehicles.

Now, I may be taking your comment out of an assumed context, but you do know that OHV ATVs, Side-by-Sides and dirtbikes use oiled foam air filters and those vehicles are run in FAR WORSE dusty conditions than on-road vehicles. Heck, I just returned from a 6 day ATV riding trip in central CO and here is the result of 6 days of riding on an air filter. Picture is a comparison of my second cleaned and freshly identical air filter. This was from about 500 miles of trail riding. And yes, the oiled foam air filters do an excellent job filtering the air.

They all catch something. How much passes is the issue. Any excess oil can really mess up the sensors or valve body.

yes, OHV's very often have oiled filters and they work (at least for me) very well in the conditions they are designed for. But in context, Mine are good for anywhere from 200-500 miles of dusty conditions before they are plugged bad enough to cause the bike to run rich. The foam is quite thick, and the "oil" is definitely different than K&N oil. very very very sticky stuff. They do an excellent job of filtering in this case, but the OHV was designed for that type of filter use from the start and expected to be changed very often under most conditions. What works in one case may not be very practical in another case. And these engines are often lucky to get 10K miles on them in their lifetime, not 100-300K miles.
