It is so obvious and simple that it might be throwing you for a loop.... Punch down on the tabs and pull backwards. The clips are like two arms holding the MAF in place. It will come out simple.... If you are hurting your fingers, you can use a flat-head screw driver (GENTLY) to help pry them back. Be careful not to bend or break the tabs. They are not delicate but will bend with pressure.

Hope that helps!
