Stitt is already a well known player in de industrial spark plug market for a very long time. Unlike most others, Stitt technology is not based on automotive activities as it only carrier an industrial spark plug line. There is no other manufacturer that carries such a large number of different plug models. Also unique are the "barrel-extended" plugs that allows users to skip the use of additional spark plug extensions to bridge the length of a spark plug hole, that can be quite long - particularly in large engines.
