I have a 1986 mustang gt. It is speed density( no mass air) and i am buyinga built 93 cobra motor (400hp if i can install it).... and thats where my concern is. this guy is giving my all the computer system with the motor, and the mass air wiring and all ,.... my concern is in the proper wiring harness and if all my components will match up or what i will need to do.. Im pretty sure that its ok to go besides the mass air but just wanted another opinion

 

You HAVE to use the Cobra's mass air intake. Speed density was a mistake made by Ford before they knew any better
