probalby really doesnt matter actually. You could put a K&N on, a 3 dollar fram, napa gold, or whatever. Unless your doing some heavy modding, you will be fine with a paper filter. I use Purolator, because I just have a thing about fram that i wont buy them.
I've had the K&N drop in on my ranger, didnt notice anything, i've also had the whole intake with the cone K&N and also didnt notice anything.
Think about it like this, the paper filter is probalby about 10"x10", the tube that connects to the intake is about 4-5" in diameter right? The hole the air has to go through in the throttle body is probably only like what 3" or so, maybe 2-2.5". Where's the restriction at?
The answer is not the filter or the intake tube.
Either way stay away from any filter that uses oil. They dont filter as well, and they coat the MAF with oil as rangerpilot said.
That Dryflow does sound interesting though... Even with what i just said, i'd probalby spend 40 bucks on another drop in filter thats supposed to give you 10% more horse power!

I use K&N filters in all 4 vehicles. When clean and reoil follow the directions. I let mine drain while I check lights and change oil. I shake them out every 15 minutes to make sure there no excess oil on the filter. No problems so far.
Yes, I know people that think more oil is better and then when the MAF gets oil on it they blame K&N. I have read the service bulletin from GM about this and it states they don't clean the MAF for free if there is a filter uses oil installed.
So far the only problems I have seen is the owner using too much oil and then not letting it drain off.

I've seen plenty of people have over-oiling problems with K&Ns straight out of the factory, so it's not merely an over-oiling issue from the owner.

A whistling noise indicates air rapidly being sucked or blown through a small hole, i.e. a leak.
that aint good, i know what ill be doing after work today
