Abstract
A spark plug is provided having an insulator with a center axis. A center electrode is coupled to the insulator and has a second end extending from an end of the insulator, the center electrode having a first tip member. A ground electrode is spaced apart from the center electrode, wherein the ground electrode has a first portion extending substantially parallel to the center axis and a second portion extending on an angle from the first portion and relative to the center axis. A second tip member is disposed on the second portion of the ground electrode such that the first tip member and the second tip member cooperate to form a gap.
