STIHL Spark Plug M 14

Original STIHL M14 spark plug, used in most garden equipment with two-stroke engines from renowned manufacturers such as STIHL, Husqvarna, STIGA, Alpina, Oleo-Mac, Dolmar, Demon, etc. The spark plug can be unscrewed with a 19″ wrench.
ATTENTION! Some STIHL tool models (usually newer ones) use a spark plug with a narrower and slightly longer thread (screwed in with a 16″ wrench) and the spark plug offered here will not be compatible. Please check; if in doubt, send us a photo of the spark plug and we will provide guidance.
