If you follow my suggestion you will be close enough - and will only have to use a torque wrench on 1 plug...................

Right, that's all I use.

I checked them once after doing it freehand. I was a little light, like 21-23' lbs.

Surprised, thought I would be heavy if anything. I have some nice torque wrenches btw. Those cheapies can really F things up. Have to be careful there.

Patrick has the the F150 plug socket or one like it. Not to long ago, a company called OTC (I think) made an 4.6/5.4 plug socket. 8 years ago or so. Think I still have the advertisement somewhere lol.

I got a 3/8" TW and a few extensions to use. The reason I really asked this question is that I have been reading on here people just snugging up the plugs then giving it another 1/4-1/2 turn, done! I really wonder how close to 28ft lbs they are getting....
1/2 turns closer. Denso's have the same tapered plugs as the Motorcraft of course. Their suggested torque is below 15' lbs from what I recall. Right on the plug box it says to tighten 1/4 turn after seat.

To get your 28, it's closer to 1/2 turn IMO. Your real close, maybe one more little nudge ? Nahhh.. lol
