First, why are you taking pictures of spark plugs in your bathroom?

I took the picture and increased the contrast for a better look. It doesn't look that bad, but if the center electrode (where the arrow is pointing) is rounded off as it appears to be in the pic, then the plugs need to be replaced.

I may be wrong but i think thats too big a gap.

I thought i'd seen people here put a .040 gap if not a .045 gap
