Claim:
1. A spark plug for a gas-powered internal combustion engine, comprising a center conductor, an insulator surrounding the center conductor, a body surrounding the insulator, a thread arranged at the front end of the body for screwing into the internal combustion engine, a center electrode connected in an electrically conductive manner to the center conductor, and at least one ground electrode that is connected in an electrically conductive manner to the body and forms a spark air gap with the center electrode, wherein a shield that shields the spark air gap in the radial direction of the spark plug is located at the front end of the body, wherein the shield includes a plurality of shield components that are attached to the front end of the body adjacent to one another in the circumferential direction of the spark plug, wherein each shield component includes a pair of major sides with an inner major side and an outer major side, and a pair of minor sides, the inner major side and the outer major side are parallel to one another with the inner major side being closer to the spark air gap and wider than the outer major side, wherein the pair of major sides are perpendicular to a radius of the spark plug.
