More performance parts

One thing I wish was more avaiable, even as a dealer option, is more Ford Racing Performance Parts. Like cold air intakes, pulleys, headers, shifters, exhaust, more aggresive tune ect avaiable when you buy your car with a warrenty. I know like many people my age I put these things on the car as soon as i get it. Why not sell it as a option when you get the car.... for example, the bullitt mustangs had a cold air intake and exhaust and better tune factory. So make it an option on more vehicles.
