NGK Iridium spark plug with a laser-welded iridium fine-wire center electrode for reliable ignition and long service life. Built to resist spark erosion thanks to iridium’s extremely high melting point.
NGK Iridium spark plugs represent a premium technical solution for riders who want consistent ignition and longer service intervals. The iridium alloy tip on the center electrode is laser welded using a special process, helping deliver a precise, reliable spark while resisting wear. Since iridium is among the hardest metals and has a very high melting point (2450°C), it is especially resistant to spark erosion—one of the main causes of spark plug performance drop over time.
If you’re looking to reduce maintenance frequency and keep your engine running clean and dependable, an iridium plug is a smart upgrade compared to conventional nickel spark plugs.
