yes, I am running one, but not for long, i believe...I get no perceptible increase in perf ( but did not expect one) but am getting 10-15% less gas mileage...with no other real benefits it's not worth that decrease....I am running the airraid dry filter...no noise change either...

The oiled will flow the most air, but they're both supposed to out-flow the OEM. I have the AFE DryflowS which should be similar to the Airaid dry, I plan to bring it to the dyno and do a direct before/after comparison for final independent proof one way or the other.
If anyone else want to get in on this testing, PM me and we'll coordinate you getting your filter to me. I'll send it back after performing a dyno run with it. I did something similar back in the day on an Evo VIII and learned quite a bit after testing ~10 air filters.

They both flow more air than the car can handle. Airraid told me 4 to 6HP max and also told me that you shouldn't buy their filter for power increases. You buy it for good filtration and the ability to clean it and no need to buy replacements.
If you buy it, I would not be looking for a noticeable power improvement.

When I performed a similar test last time the car remained strapped to the dyno the entire time with the start/stop RPM the same. Each filter got 3 pulls with the paper filter going first and last to act as a type of control/verification. Dynos will never be exact, but performed properly they're far more accurate than the butt dyno.

GM spends much time and money looking at each individual component and what a simple change to a single component has on the entire system. The aftermarket does not do this.

First pull with the stock GM LS7 paper filer.
Second pull with an oiled cotton gauze air filter element installed. Picked up 2 HP over the stock filter.
Third pull with the GM LS9 air filter element installed. Picked up 2 HP over the aftermarket oiled cotton gauze filter.

Oiled does flow more air but you will hardly notice it. The bad thing about the oiled filters is they collect a ton of dust and that builds up and they get dirty much much much much faster. So after time, they actually flow less air as they get clogged faster than the non-oiled.
Definitely not worth it unless you buy one to only use at the drag strip.

Beside Glen, I saw one other person on another thread, claiming no difference in power and decrease in mpg. Another person on another thread claims slight better breathing.
I just installed mine, and I noticed no difference at moderate to heavy acceleration. However, at low gear and low rpm; ie. 60mph on 6th or 7th gear, a slight push on the throttle results in a definite slight increase in response. I don't have it long enough to check for mpg differences yet, but I think it's a keeper for me since I drive mostly CA highways, and that usually means 6th or 7th gear.
I wonder whether having a manual or auto makes any difference here? I have a manual.
