As any movie fan can tell you, Steve McQueen was the King of Cool, and he was at his coolest in Bullitt, driving a souped-up Ford Mustang. Now, if you want to emulate your hipster hero, you, too, can drive a Ford Mustang Bullitt, a limited edition GT that is not only smoking fast, it's also a sweet drive, especially, with the Ford Mustang GT cold air intake under the hood, boosting the horsepower as well as extending the Bullitt's 15 City/26 Highway MPG. How much the Ford Mustange GT cold air intake increases the mileage is an open question, depending on many factors, including your driving habits, the kind of gas you normally buy, what kind of carburetor you have, and how you've modified your engine. At any rate, adding a Ford Mustang GT cold air intake makes sense for other reasons as well. For example, a Ford Mustang GT cold air intake will also make your engine run cooler whether it's on the highway, or you're just going around the block for the paper. A cooler engine will have a longer life that one that runs hot. Any mechanic can tell you that. So if you want to make like Steve McQueen, then get yourself the limited edition Mustang Bullitt with the Ford Mustang GT cold air intake under the hood. Go faster and further with a cooler engine!
