How many times do we have to cover this topic? I am certain the search button would have pulled up at least 3 threads regarding that same question.
By helping the efficiency of the engine, you will in theory create more power. If you are making the same power, at a lower RPM... you in theory will save fuel... Less gas to accomplish the same power load... will you gain a noticeable amount of economy from an intake? I gained maybe a 1/4 mpg from the intake... MAYBE.
If you get an intake, and get on it just to hear it suck in air, you will lose mileage. Most of us did it at first. Some still do I am sure.
If you want more MPGs, search for the hypermiling thread... by changing some of your driving habits, you will save more than an intake could.

Another thing people forget to compare is engine size, tranny, gear ratio, driving conditions, etc..... I'm sure my cia would get me a tad better mpg if I would keep my foot out of it. I bought a v-8 truck, not a 4cyl. car....

I got up in the 25 MPG range by changing my driving habits. Do what eric said, search hypermiling. Basically :
1) Run tires ~5# over stock pressure (any higher risks uneven wear)
2) Accelerate *sllooowly*. Make 55 just as you reach the end of highway ramps. If you have a stick, shift at 2000 RPM or less. Light foot is the key.
3) Cruise at 55 MPH. 60 absolute max.
Also, don't expect wonders in winter or hilly country. I got 25 MPG for one tank, but it was 80% expressway driving in flat *** South Carolina. If you have 4WD with an automatic, you won't be able to do as well as a 2WD manual. I actually stopped doing it because it's just not safe sometimes, especially on the interstate.
