Essentially the best air filter is the factory style. The box is pretty good at keeping water out (if you seal the holes in the bottom), and it's a quality filter.
The vast majority of aftermarket filters absolutely suck at filtering. A Jeep doesn't really benefit from it, and most "cold air" intakes are just a marketing term and it's still a hot air intake (how exactly does taking out the factory filter and putting a filter in exactly the same place make it any colder? It's total BS).
Aftermarket filters are for bling, or to gain room in your engine bay for suspension, engine upgrades, etc.
Your MPG is very unlikely to change at all, and if you're very lucky, you might gain a low single-digit number of horsepower.
