NGK
NGK manufactures spark plugs and spark plug wires, as well as glow plugs for diesel applications. Their range of spark plugs cover everything from OEM replacement to Ultimate Performance plugs, and are available as traditional copper, platinum, or iridium tips. NGK’s reputation as an OEM supplier for many car manufacturers makes them a top choice for spark plugs. Few brands can make that claim and have the quality to back it up.
