I bought some new NGK's. When I got home I noticed the box says NGK 5553. Is this correct? I had asked for NGK TR55. Stupid me for not double checking at the counter.

Sounds like they gave you the wrong ones.

They should say TR55 on the box. Might want to double check if you haven't isntalled them yet. In any case they will run, just maybe not long. If the heat range is terribly off they'll foul out.

Thanks, they were the wrong ones. I went back and swapped. I just put the TR55's on. GM out to be flogged for the lack of room to swap plugs. It took me awhile, but I got the new plugs in. I really did not notice any difference. I also tweeked the TB and Fuel again. I will be going back to the track on Thursday to see if there is a difference.
