Dirty Spark Plugs?

Hi, what are the effects of dirty or spark plugs that need changing on your car?
How would you know you need to change them, besides pulling them out and looking at it. Will fouled spark plugs effect your emissions and smog test? Will new spark plugs effect it? Oh yea, and what will running all bur7eq spark plugs do to your car? answers please.

you need to change the spark plug when it is due at every 30k miles or so. You will need to check by pulling the spark plug out. Yes the spark plug can affect your emission. New spark plug will definately help. bur7eq for leading and bur9eq for trailing
