The dry filters seem to be a lower flow than the oiled ones. The oiled ones actually use the oil to catch the dirt and holes in element seem to be made bigger for more flow whereas the dry ones use the element to catch the dirt so they can't be as big of holes. Some will argue that the dry ones catch more dirt and that the oiled ones will let too much thru and can damage your engine or erode your turbo. I am not here to argue that point but I will say after over 100k miles of driving with an oiled k&n filter, I have had no issues. It's up to you if you want to fork out the money and try both but I think that this whole debate, which has been done over and over, would be totally based on opinion and personal experience and personal preference. Not starting a debate or trying to hijack, just telling the facts.

I have used k&n filters on 3 vehicles, 97 ranger for about 30k, my 04 f150 heritage for 25k and my 08 f150 for the whole life of it and it is now at almost 80k. 2 of those were cold air intakes(both f150s) and 2 were drop one(ranger and 04 f150 for about 5k before I bought the intake to replace it). I have had 0 problems except for one which was my fault. I used a hose clamp to hold the intake on my 08 and I tightened too much so it put it against metal and spread apart part of the element, more than I was comfortable with leaving that way so I replaced it.
