    All three? There should be four spark plugs.

    I can't imagine what you could do installing them that would cause them to break 150 miles later. What plugs did you use? I can see how the wrong ones could wreak all sorts of havoc.

    Also, that plug sure looks dirty and beat up for only 150 miles. Is there more to the story?
