NGK spark plugs are the first O.E.M. choice of most motorcycle factories — proof of their high build quality. NGK makes spark plugs for every car, motorcycle and marine engine, and for practically any engine at all. To cover the different needs that philosophy creates, 14 factories were built in 8 different countries. Today the company has state-of-the-art production plants, warehousing and distribution channels, and remains committed to giving its customers the best products with the best service.
