My opinion is it's not going to flow any better than a regular filter unless you get a bigger filter (like a cone style). The only advantage would be the ability to clean it, and maybe it might filter a little better.
According the guys at AEM filters. The major restriction in the stock Jeep system is that flexy rubber pipe that connects the box to the throttle. All the little ridges cause turbulence in the air making it harder to push through. Also when I was talking to the rep he said they have a new dry flow system for the Cherokee, that is almost ready to release. He said if all goes as planed you will be able to find it later this year.
