摘要

The invention relates to a spark plug (1) comprising an insulator (12) and a housing (2) that is provided with optically readable data in the area of the insulator (12) and/or of the housing (2). The spark plug (1) is additionally provided with at least one data carrier device (14A, 14B), which is provided as a separate element in the area of the insulator (12) and/or of the housing (2). At least a portion of the data can be placed on said data carrier device before and/or after the data carrier device has been placed on the insulator (12) and/or on the housing (2).
