+ fuel economy... but b4 you get ready to buy one, think about what kind of wheeling ur doing... if you like mud/water, you may want to put in a snorkel instead... you will get pretty much the same air flow and fuel economy, depending on the brand too
don`t forget to talk to your dealership too, they may completely void the warrenty.. mine was awesome they said I could do anything i want as long its not caused by a mod..

A CAI would give you cooler air which would be more dense and therefor would seem to give your engine better performance.
Aftermarket cold air intake systems are marketed with claims of increased engine efficiency and performance. The putative principle behind a cold air intake is that cooler air has a higher density, thus containing more oxygen per volume unit than warmer air. Most of these systems however are mounted within the engine bay where the air is very hot, and are really a short air intake. As far as giving the engine more air, it would be very hard for it to do so as the intake runners are still the same size, and there is nothing, short of a supercharger, to increase the flow of air to the engine.
As to the question why a CAI, if you are only talking about the setup which most people install in the engine bay, and then claim an increase of 10-20HP or so, I would have to say.

I'm not a fan of CAIs if you off-road in water. In fact, here in Oklahoma even heavy rains could be problematic with a CAI. Too many horror stories of hydrolocking. But, as for the snorkel being a better solution: Just be aware that there is a HP penalty with the snorkel. At least, that's what dyno testing by RIPP has revealed: About a 30-HP loss as compared to the CAI that the RIPP supercharger comes with. That's dyno testing, and doesn't take into account any improvement from ram air at highway speeds. If you search around, there are threads with several videos that discuss this thoroughly. Of course, the need for air w/o the SC is less, so the impact should be less.

Cai ?
I would rather save money than spending $ 300 on a CAI. It might improve in fuel economy I would say 10 miles to a tank, it would pay off in the long run. But like this guys have said, what do you do with your jeep ? If you are planing to go through water I would not recommend it. About performance obviously is not meant for speed. I rather save the money and spend it wisely on other parts unless of course you have money to spare.
