1. A spark plug comprising a housing, an insulator for electrically insulating a center electrode provided at least partly on the inside of the insulator, wherein the housing is configured such that in a mounted state, an annular gap is formed between the housing and the insulator, characterized in that the annular gap is filled with a heat-conducting element proximate a distal end of the insulator where the center electrode extends past the insulator.
