New revised part # OEM coil arrived.
I thought about getting some gold heat tape and putting some on the top part of the coil that is exposed but I don't have any and it would take a few days to order and ship, and I wanted to fix the P0351 as soon as possible.
Only one 10mm bolt holding it in. I just replaced it myself rather easily in about 20 minutes. Removed the three 10mm bolts holding in the ECU on the black fuel rail cover carefully after stuffing some shop towels below to catch any dropped bolts. Zip tied the box out of the way on the strut brace so it doesn't slide into anything. Then I grabbed the coil and pulled it straight out and then up to get the whole thing out. Pressed the connector down and pulled it off and the new one went back in just as easily. Just need patience and dexterity and it's pretty painless. The drivers side coils wouldn't be as easy, though, since there's more stuff in the way.
I put everything back the way it was and secured all the bolts before starting it again. Then I went for a drive and got everything nice and hot before doing a couple WOT pulls to redline and all is well. No more CEL.
