The 70mm Cobra mass air sensor be design is also quite restrictive for it's size.
I bought a mass air sensor pigtail(plug) from a Ford dealer. Got an aftermarket sensor and free used mass air intake bellows from a friend who went with the chrome cold air thingy-dingy. Then I bought a used mass air computer for like 50 bucks. Now all you have to do is add and remove a few wires in the main wiring harness and Viola' MASS AIR! CHEAP!
If you wanted to do it that way email me or post when you want to do it and i'll type you complete instructions.
