The gap is pre set on these plugs
Passanger side front to back 1234
Drivers side front to back 5678
Your misfire is the rear most drivers side
The 2013 has the adjustable gap plugs, best to check the gap on them and not trust them out of the box. Our 2007 have the fixed gap plugs as well as many 2008.

Oh damn, I didn't know they changed the entire plug style.
There is a lot of good information in the Owners Manual

.041 thousandths is gap for 2013 5.4 motor. Like JExpedition said, you always check, Many times I saw parts hit floor. I can't tell you back when I sold parts, that packs of plugs hit the floor when pulling them down off shelf. Depending how they hit floor either nothing changes, or the gap gets smashed down .020. And on top of that package looked fine after fall. Oops!

I always use a timing light to check for bad plugs or wires. Sure fire way 100% accuracy too.
