Patent ID: 8519607

Claim:
A spark plug, comprising: a metallic shell having an axial bore; an insulator having an axial bore and being at least partially disposed within the axial bore of the metallic shell; a center electrode being at least partially disposed within the axial bore of the insulator, the center electrode comprising a center electrode body having a longitudinal axis and an axially-facing free end surface; a ground electrode being attached to the metallic shell, the ground electrode comprising a ground electrode body having a longitudinal axis and an axially-facing free end surface; and an electrode tip assembly being attached to the axially-facing free end surface of the center electrode body or the ground electrode body and having a longitudinal axis that is generally perpendicular to the longitudinal axis of the respective electrode body to which it is attached, wherein the electrode tip assembly comprises an electrode tip body attached to the respective electrode body and a noble metal firing tip attached to the electrode tip body and facing a spark gap.
