Somebody made a good point in another thread regarding K&N filters. If it flows more air, it's flowing more dirt.
I used K&N's in two Dodges and a Ford that I had. I saw no real differences in power.
It was just me, but I tended to let their cleaning go beyond what should have been. As a result the K&Ns were pretty cruddy when I finally cleaned them out.
I think it may be just more convienant to pull out the old and drop in new on a regular basis.
I think I may just stay with factory in the JK.

K&N filters started on the track, and of course caught on from there. Hey if the race car drivers are using them, they've gotta be good. Right?
Let's not forget, after the race, most of those engines are torn down, and rebuilt. Any filter that allows more flow through the filtering media, does so for a reason.
We sometimes get caught up in the hype, thinking that by purchasing an air filter costing three times more than a stock filter is going to net us more power.
Sure all the motorhead shows on TV say that. Don't forget those shows are sponsered by quite a few companies.
Keep the stock filter, and save the money for gas.

As my 07 racked up miles the MPG got better. From 14-15 when I first got it to 18-19 now if I drive conservatively. I have 21,000 on her now.
What I'm tyying to say here is that there are a lot of variables that will effect mileage. A K&N might help or might not. Its a crap shoot.
Ultimately it just comes down to your preference.
