Just changed spark plugs at 13,500 miles..are these in bad shape?
Lately my car's been giving me poor gas milage and felt a bit rough.
I've decided to change my spark plugs today and when I pulled
the old plugs, they looked pretty worn out.
I am no spark plug expert so I would like to ask you guys
how bad of condition these are in.
Here are the pics:

The plug electrode color looks good! That whitish-grey color usually indicates complete combustion without the imxture being too rich or lean. When you say "they looked pretty worn out", what do you mean??
You should be more concerned when one or two of the plugs shows a different color (ie. sooty black or extremely white). My guess is that you just spent some money on a replacement you didn't really need...
