      Any cheaper rails for a 2001 cobra?

      would this be the correct kit for my 2003 mach 1 ?

      • The Aeromotive High Flow Fuel Rail Kit is designed to only work with the 1999 to 2004 Mustang Cobra. The cobra will have the same identical motor as the Mach 1, but the Mach one has other features in the engine bay such as the shaker hood and ram air system that will not allow this kit to work properly.

          Great product

          Quick and easy install. Only time consuming factor is getting to the passenger side rails.
