Isn't the inlet on the Cobra more suited to a 65mm? In any event, smaller will hurt you less than bigger (bigger will kill your bottom end power). I vote 65mm as well.

On the Cobra intake, stock the bore is 65mm freindly, but if you plan on adding a blower or NOS, some port work is in order. Then, and only then, go with the 70mm. Otherwise you will have serious launching problems! As in massive wheel spin, trust me!! As far as the MAF goes, it's really your call, but I wouldn't go over a 77mm. Stay around 75mm and you will be better off(depending on your mods).

65mm throttle body. if you are getting a C&L 73mm it is probably as good as a pro-m 80mm
