Only two items underhood distinguish the Bullitt from a standard Mustang GT. Most obvious is the Ford Racing strut-tower brace, which is adorned with a plate that displays the car's VIN and Bullitt serial number. That should prevent any complaints like the ink wiping off the shock tower stickers on the '01 Bullitts. What probably caught your attention is the new Ford Racing cold-air intake, which features an injection-molded airbox and a disposable paper air filter, which is dark in color to hide dirt. There might be some power in an aftermarket filter, but the airbox looks tough to beat. It stayed cool to the touch even after repeated dragstrip runs.
