IRIDIUM SPARK PLUGS
BETTER METALS MEAN BETTER
SPARK PLUG DESIGNS
  • Six times harder than platinum, iridium
  • doesn’t melt in temperatures up to 4,000° F
  • Because the iridium electrodes of these
  • plugs can be shrunk 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
  • Use NGK reference chart to order and stock
  • these plugs
