Abstract

A spark plug for igniting gases in an internal combustion engine is disclosed. The spark plug has a center electrode, an insulator, a one-piece shell, and a terminal. The center electrode is in communication with an energy source. The insulator surrounds the center electrode. The one-piece shell surrounds and contacts the insulator for securing the insulator within the shell, wherein the shell has a plurality of threads near a first end and a ground electrode attached to the shell and aligned with a tip of the center electrode at a second end to define a spark gap. Further, a seat is formed in the shell between the plurality of threads and the ground electrode for sealing the shell against the engine. The terminal has a first end in communication with the center electrode and a second end which has a connector portion for connecting to the energy source.
