Hey Ford Techs! 2005 5.4L Ford striped spark plug

Yes...
Funny thing is, it hasn't run this smooth at idle for a long time. When I had the plugs changed back in August, it was an attempt to get it to smooth out along with injector cleaner, fuel filters, etc.
So my WAG is the plug was bad from day one. I'm already seeing about 1 MPG increase in similar driving conditions.

Where I got hosed is when I took the truck in with 48K on the odometer, just before it ran out of warranty. The Ford dealer service advisor told me there was a recall on the plugs and they would all be changed under the recall. So when I changed the plugs at a little over 100K miles, I thought it was the second set of plugs. Wrong. The plugs pulled out were the originals. So some Ford tech flagged Ford for the hours, probably turned in some plugs that were in his tool box and I went home thinking I was set for another 50,000 + miles.
