Abstract
A spark plug housing. The spark plug housing includes an inner side, an outer side, and a longitudinal axis, which extends from an end of the spark plug housing facing toward the combustion chamber up to an end of the spark plug housing facing away from the combustion chamber. The spark plug housing includes a circumferential shoulder on its inner side, which is designed so that a spark plug insulator rests thereon, and a corrosion protection layer on its inner side, which is formed on a section of the inner side of the spark plug housing, the section extending from the end of the spark plug housing facing toward the combustion chamber to at least over the shoulder and along the inner circumference of the spark plug housing.
