wow. okay the MAFS (mass air flow sensor is very crucial to your car, i don't think that it will start without it. just remove the stripped screw and replace it with one at you local home depot. and mount it in the hole provided in the new intake. but when you tighten the MAFS into the hole do not tighten to hard or it will break the arms of it off and you will be more screwed. read how to install in the "installs" forum i guess. GOOD LUCK!
