How do my spark plugs look?
Finally got around to doing the plugs and leaking valve cover gaskets on my Infiniti. Here are a couple of the old plugs. I presume they are the original ones. What does the white crust mean?

You could do that to make the plugs look pretty, but it would nothing for the functionality. If you are going to do something to make the plugs work better, you need to dress the anode and electrode with a file and then re-gap.

I'd be willing to bet that gap is around .055 to .06
Probably original plugs.
Swap them with some NGK iridium plugs and be done with it. Assuming you're not having driveability issues at the moment.
You can always pull the front ones in a few miles and inspect them then. If it's a tuning issue the crust will return. It can be dealt with then.
