I have been looking into adding a cold air system. I have a 2012 Jk and I was wondering if anyone has noticed much gain in horsepower and fuel mileage. Does anyone have a preference (airaid,banks etc.) is one better than the other. I am just doing a little research to see if it's worth the money. And trying to see what kind of fuel mileage gains I would get.
