1. A spark plug electrode, comprising:
an electrode base that includes a side surface with an opening;
a heat dissipating core that is at least partially located within the electrode base and includes a core main body with first and second elongated sides and a core extension, the core extension diverges from at least one of the first and second elongated sides of the core main body and extends at least partially into the opening; and
an electrode tip that is attached to or formed on the side surface of the electrode base such that the electrode tip covers the opening, wherein the electrode tip is directly thermally coupled to the core extension of the heat dissipating core through the opening.
