SPARK PLUGS
  • Superior construction for serious power
  • IRIDIUM IX SPARK PLUG
  • NGK makes plugs for almost every application and
  • The ultimate in spark plug technology and
  • riding style
    performance from the industry leader
  • Versatile plugs with wide operating heat ranges
  • The iridium electrode is 25% smaller than
  • prevent fouling from running too cool and
    a platinum electrode, and it’s just 1 / 4 the size
    preignition from running too hot
    of a conventional nickel electrode
  • Feature high alumina ceramics for improved heat
  • Ultra-small diameter center electrode reduces
  • dissipation and electrical insulation, deep-seated
    voltage requirement and extends ignition
    copper core for a wider heat range and a nickel alloy
    system life
    tip for longer life

    IRIDIUM SPARK PLUGS
  • Six times harder than platinum, iridium doesn’t melt in
  • temperatures up to 4,000°F (2,204°C)
  • Because the plug’s iridium electrode can shrink to only
  • 0.4mm, voltage requirements decrease while firing
    performance improves
  • 360° laser welding of electrode provides a seal that resists
  • wear even in the worst conditions
  • Ground electrode features a tapered cut and U-groove
  • that form a large volume area for the flame’s center
