First step is to remove all 3 bolts holding your plastic 5.4 cover (over the throttle body). These are all 8mm. Removing air intake: Now we need to take the air intake off to have room to work. 1.) Pull out the two hoses at the top of the intake. 2.) Unplug the MAF (mass air flow sensor) plug 3) Then unclamp the clip that holds the air box/filter in. 4) Finally loosen up the C-clamp attaching to the throttle body with an 8mm socket.
