Now that's a good question. Speaking from experiance on my 5th gen camaro SS. That was my DD in stop and go traffic. Around 15-20mph. When the vehicle was stock i was seeing 13mpg city/hwy. At normal speeds on the Hwy i would see around 17/18mpg on an average of 25- 70mph but would soon drop down to 13 in stop and go traffic.
When i put on the CAI(Cold Air Inductions inc.) i noticed an improvement on the dead spot and began noticing a slight increase on the mpg(stop n go) of about 14 maybe 15. This all depends if you gun it all the time or have a heavy foot. I'm speaking for myself and i did drive spiritedly occassionally but not always. This will all depend on your driving style folks. These intakes may offer roughly about 8-10 hp/tq increase. Manufactures may advertise more. I would suggest getting more info from them.
As far as maintenance goes, i've owned K&N and from what i remember i believe the air filter is good for up to 25k before it needs to be cleaned. I personally do not like the cleaning process of oiling the filter and if you accidently over oil it, it can potentionally damage the MAF sensor. (New to Jeep, not sure if these are on these vehicles.) So i would prefer to spend $40 or so on buying just the filter and installing it to the intake.
For me, personally i am considering purchasing one in the near future and can care less what anyone thinks of them, just debating what brand on getting and what is available for the jeep. I've spent countless hours under the hood of my rides and know what i put in them and what they will do after, just my 0.02
