Abstract
A spark plug assembly for an internal combustion engine has a housing, an electrode, an axis and a conducting member radially oriented relative to the axis has a collar disposed about the axis and connected to an end of the housing. The spark plug is connected to the engine and exposed to a combustion chamber of the engine. The collar extends a predetermined distance from the end of the housing and shields a gap between the conducting member and electrode from air swirl introduced into a combustion chamber.
