ABSTRACT:
Exemplary embodiments of the present invention provide a spark plug for use in conjunction with an internal combustion engine, and, more particularly, to a spark plug having a structure providing improved ignition capability. In one particular configuration, a spark plug is provided forming a gap between a center electrode and an insulator of the spark plug. However, it will become apparent that other configurations are contemplated as well, as shown and described herein.
