I used to be a huge beliver in K and N. While I think the filter itself is build well and they have their place in cold air intakes, etc. I think that you have to have the perfect oil content in the filter to get a good balance between airflow and filtration. Too much oil, restricted airflow, dirty MAF sensor, etc. Not enough oil, great airflow, not great filtration.
I am sticking with paper for now. Prices are high, but they should come down.
Oh, and on the two trucks I had KandN filters on, i noticed no increase in anything.

"Socialism, like the ancient ideas from which it springs, confuses the distinction between government and society. As a result of this, every time we object to a thing being done by government, the socialist concludes that we object to its being done at all. " -The Law, Frédéric Bastiat, 1850
