Starting with a single product in 1936, NGK® became the world leader in innovation, technology, and premium quality in the manufacture of spark plugs for virtually every automotive manufacturer in the world. NGK`s extraordinary growth can be attributed to a philosophy of manufacturing the product where it is going to be used, which means a substantial number of products sold in the USA are made in America.
