I have a stock non pp and I want to change the plugs out. Is the .35 gap recommend for stock or has anyone used a different gap for stock applications? Not sure if mine have ever been changed

OK cool I just wanted to make sure. Any brand better than others. I know Motorcraft is what ford always says has to go in but not sure if anyone has better with others

Changed out the plugs today, very easy! All the plugs that came out were about a .30 gap. Made sure all new ones were .35 (ish) anyone see the plug out of the box at a .30 gap if so was I wrong in changing the gap at all?

Perfect. Dose seem to like the new plugs. Like a new hair cut... same person but just a little smoother!

The Owner's Manual of my 2016 states the spark plug gap is spec'ed at .030 - .033. Is this another recent change? I pulled the front three last night, and they were at .029 - .030.

I just finished checking all six of my plugs. I have to say I was a little surprised by what was found:- As mentioned earlier, all of them were found to be at no more than .030" gap, while the Owner's Manual specs the range at .030 - .033". Most were at .029"
- None of them had any anti-seize or dielectric anywhere.
- Two of the rubber sleeves on the coil packs were crushed/folded under themselves.
- I found what I consider to be a significant amount of carbon around the end of the plugs. The engine only has 2,200 miles on it, and I just didn't think this much carbon would already be on them. (ABOVE)
In the end, I gapped them all to .0315", cleaned off all the carbon I could, and re-installed them with anti-seize and some dielectric. Now to go drive around for a while and see what , if any, benefit there will be.

Besides you are still in the honeymoon phase at 2200 miles. Besides the fact that the plugs are encouraging a "rich" burn, there's also the general motor breakin (yes yes modern engines don't require breakin etc). I too found the rubber sleeves folded over on a couple of the OEM COPs on my ride, but I don't think it hurt anything.
I think the part that folds over is the replaceable boot? I had one folded over, but the dealer installed all new boots when the did the valve cover gaskets. They were replaced due to oil contamination. Mine all look good now.

No, I'm pretty sure you're talking about the wire boot, which is the replaceable part at the spark plug end of the assembly.
SHODDED and I are referring to the rubber sleeve that is at the other end of the assembly, the top as is sits in the engine. This rubber sleeve looks to be a seal for the assembly, but apparently is quite often found to be pushed down on itself, folded over/under.
