I may have found the root cause: defective torque wrench? I tested it on another bolt and set the torque really low to trigger the "click". The audible "click" and feel was ever so faint. To put things into perspective, I had to test it about 3-4x to notice something. The audible click i'm used to is from wheel bolts on my craftsman t-wrench.
That being said, I'm sure that I over-torque the spark plug because I was waiting for the "click". Common sense eventually kicked in; however, I went a few 1/4 turns thinking nothing of it because the hand tight was a little slippery from dis-assembly schmutz.
I spoke to the dealer this morning and they will start the work on Monday. I will follow-up with spark plug enginerd at work and ask for an opinion.
