3.5 Ecoboost Spark Plug Change 15-17 Expedition/Navigator/F150

Replacing the spark plugs on my 193k mile 3.5L Ecoboost Expedition. Very easy procedure. Need a 5/8 Socket, extension, and socket wrench. 8mm socket for the ignition coil bolts. Preferable to do when the engine is warm to aid in removing spark plugs. Would spray PB blaster down the plug holes before removing plugs if you think they are going to break or be stuck in there. All of mine came out no stories. Just another quick DIY to show you that the dealer is not your only option. Very easy to do at home. This got rid of my partial throttle shudder and popping when going to accelerate.
