This is the "cherokee" section not the "grand Cherokee" section, that is one click below cherokee tech....just saying.......but yes a CAI will do better mpg for any car. not much, maybe 1, 2, 3, mpg......

x2..
Instead of throwing parts at it, find your problem and fix it right.
It would also help if you posted this in the right area, Maybe a mod can move it for you..

x2 Don't throw parts at it, run a few tests and see why it's doing so bad. Could be O2 sensors or a number of other things. And a CAI will technically raise MPGs, but that's only if you can lay off the skinny pedal! When I put mine on, all I did was floor it because it sounded cool, haha.

A CAI will not get you anywhere close to 1, 2 or 3 MPG boost. The best modification for improved fuel economy continues to be the driver modification or an egg on the dash. I have no idea where you live, but cold weather could play a part in it too.

So robertJ your telling me that there is no chance that when i put a CAI on my jeep that i will even remotely get 1mpg better??? are you joking me? The stock filter box on the jeep was so restricted it wasn't even funny, i put a K&N CAI on there and it breathed a whole lot better, so im pretty sure im getting at least 1mpg or better. Nowhere near 1 mpg boost......how do u figure?

Mike mike is right. if you've dropped that much mpg in a short period of time you have a problem you need to locate and fix.
Don't worry about the filter now...

The only reason people get better fuel economy after installing a CAI is because they start driving to get better MPG. As Metlic says, the engine's computer adjust for a certain A:F ratio regardless of what air intake system you have. It's a common myth and marketing ploy by the manufacturers to make you think otherwise. If it makes you feel better about your purchase though, more power to you.

My best advice to you sir would be to do a general tune up. If its around time for plugs air filter fuel filter plug wires ect... Change them. If it doesnt solve or help the situation and if you dont figure its your driving habits driving
more in 4wd or any other thing of that sort that may vary from time to time then you can most likely figure on it being something else starting to go.
Also check your tire pressure....not saying that one of these things could cause that big of a drop but a combination of them sure could
