Abstract
In a spark plug a longitudinal bore is arranged eccentrically in a housing. A housing part with a thicker wall thickness is thereby formed, and a pressure sensor is provided in a bore or this housing part, and therefore the pressure sensor is in direct connection with the combustion chamber. No structural outer changes are required on the housing, so that the spark plug can be installed without any problems in known arrangements.
