Abstract: A spark plug electrode includes an electrode tip that is attached to or formed on an electrode base so that the electrode tip is directly thermally coupled to a heat dissipating core through an opening in the electrode base. This direct thermal coupling may take place on a side surface of a ground electrode or a center electrode and removes thermal energy away from the electrode tip in order to reduce thermal and/or other stresses. The heat dissipating core may have one or more core extensions that diverge or branch off of a core main body and extend into the opening in the electrode base for better thermal coupling to the electrode tip. The electrode tip can be attached to the electrode base via welding or it can be formed on the electrode base using a suitable additive manufacturing process, such as a powder bed fusion technique.
