The oem Champion Copper RE14MCC4 plugs work really well, and Autozone has them for $1.99 each.
You can run them for 60K, and have no issues. Whatever the case, I would run the same plug in all 16 holes.
If I were to run Plats, I think I would research the oem Champion equivalent, and run with that.
I did just that with a set of plugs when I had my 01 D 4.7, and they were flawless for the 50K I ran them.
