It should increase mpg just because the air flows better/easier, and it's cooler, hence the name "cold air intake". However, it won't be anything big. I would say 3 at the most, if you don't drive like a crazy person. I'm sort of learning myself on things. I know opening up your exhaust can increase mpg too. That is a bit more pricey, and probably would achieve about the same numbers though. I plan on getting a new exhaust kit this summer. Unfortunately you have to have a custom one made because no one makes it for our model. As far as I know, other than keeping up on maintenance, you really can't do too much to increase your mpg unless you change your driving habits if you drive really fast, and accelerate fast.
