ignition

One of my pellets corroded, I need to use my truck, my question is/are: 1. Can I use one if the stock pellets in place of that one that is corroded? 2. Can I sand/polish the corroded pellet? I do have a replacement from Granatelli on the way. TiA!

I haven't seen anything come up on my searches for ruthenium spark plugs so forgive me if this has been posted before. My question to the community is what do you think about these new ruthenium spark plugs offered by NGK? Has anyone tried them on their raptor yet? I'm asking about 6.2L...
