A spark plug for use in an internal combustion engine having a insulator with a cylindrical body that surrounds a center electrode. The cylindrical body has a first diameter section separated from a second diameter section by a shoulder. A sleeve that surrounds the second diameter has an integral base that is positioned a fixed distance from the tip of the center electrode by the engagement of a flange on the sleeve with shoulder on the cylindrical body. A radial tab that extends from the sleeve is located in a slot in a head on a combustion chamber of an internal combustion engine to establish the position of a ground electrode defined by the base in the combustion chamber. An end nut that surrounds the first diameter and engages the flange to locate and position the spark plug within the combustion chamber.
