The products are adequately protected from combustion gas leaking through the shell thanks to triple-gasket sealing, while most other spark plugs on the market feature only two seals. The spark plugs also feature the alumina silicate insulator that is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance. To eliminate “flash over,” which can cause misfiring, these products are built with corrugated ribs and feature cold-rolled threads to prevent damage to the cylinder head and make installation and removal easier. The products also feature trivalent metal plating for superior anti-corrosion and anti-seizing properties.

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. One of the benefits of such a policy is the ability to work closely with manufacturers in developing products tailored specifically to their needs. Today with ISO 14001 and ISO/TS 16949 certification as well as state-of-the-art manufacturing and inventory facilities, NGK provides customers with the finest spark plugs and complimentary products.
