I don't really know how to read spark plugs, so I was hoping some of the gurus here could help me out. I just replaced the plugs in my '93 NX2K (140,000 miles). I put a picture of them here:

I was hoping someone could take a look at the picture and tell me if they indicate any problems.

I think they were long overdue to be replaced.

Thanks,
Ben

Actually, it's necessary to see the insulators and the electrodes. You can see them a little bit in these photos, but not terribly well. But, from what I can see they look OK.
