NGK iridium spark plugs currently represent the highest quality technical solution. They have an iridium alloy in the central electrode, which is welded in a special process with the help of a laser.
The precious metal iridium is one of the hardest metals in the world. Its melting point is 2450°C, making it especially resistant to erosion by sparks. By using this metal, the service life is doubled on average compared to conventional nickel spark plugs. TYPE OF SPARK PLUG: IRIDIUM IX Usage: Road PACKAGING: PER UNIT TYPE OF CONNECTION: REMOVABLE TERMINAL
