EYQUEM, French spark plugs manufacturer, is the number 1 in France and
5th worldwide in the spark plugs market.
For more than 100 years, EYQUEM worked in collaboration with European
car makers in developing high-performance and less polluting engines.
This confers the company the status of historical and preferred partner
of car manufacturers.
Since the beginning of the automobile era, EYQUEM joined victoriously
its partners in motor racings. The developments we realize in this frame
allow us to engineer better features into our spark plugs for standard
cars. From the very start of the engine design, our engineers work with
car makers to develop the spark plug of tomorrow.
Our spark plugs range (about 150 references) covers the whole European
car market:
