Zusammenfassung:The ignition plug has an off-center longitudinal through bore (3) accommodating an insulator with housing regions of different wall thickness and a pressure measurement device (11) in a thicker wall region (4). The insulator has several parts, at least of an upper part (6) towards the high voltage connection and a lower part (7) towards the combustion chamber. Insulating elastic filling element (9) is arranged between the insulator parts.
