Without taking the intake manifold off you will have to cut off the tube which houses the MAF. It would be pretty quick if you have a dremel, but I dont at my apartment so I had to break it off bit by bit with pliers.
Seats 1-10: 4 but long with lots of different tools.
intake 1-10: 6, long and tiring. A 4 if I had to do it again. The hard part is the baffle, the airbox is cake if you cut the tube off.
