Abstract: A spark plug having a metal shell accommodating a dielectric core through which an electrode extends and terminates at one end in a tip spaced by a spark gap from an overlying ground wire that is bent between its ends and joined to the shell. That surface of the ground wire which confronts the electrode is grooved to enlarge its area and enable the wire to react like a bimetallic element in response to changes in its temperature and vary the size of the spark gap.
