I don't think a Ford dealership will be too keen on installing aftermarket parts, and they're definitely the most expensive place to get it done. I would recommend asking around on whatever regional forum you belong to and asking for recommendations from other members on where to get it done locally. And it will most likely void the warranty too.
As far as gas mileage, it will most likely have very little impact. Some people even see gains in gas mileage with a cold air intake.
