Supposedly, and according to the study that Tas posted, the K&N is actually able to flow more air than no filter at all. I can actually believe this in some cases. Have you looked under your filter lately? It's probably got the worst fluid dynamics profile you can imagine. You'd want something there to straighten out and train the airflow to a specific direction.

I still use a T-Shirt for an air filter. It's washable, and doesn't require oil or a $50-$150 initial investment.
