Laser Iridium® Long life

Laser Iridium® spark plugs provide superior ignitability along with a super long service life. The Iridium / Platinum surfaces ensure slow wear rate, yet also provide a stable idle with superior antifouling, improved fuel efficiency and lower emissions.

  • Laser welded Iridium centre electrode tip
  • Platinum disc welded to backside of ground electrode provides long life
  • Trivalent metal plating for superior anti-corrosion and anti-seizing
  • Faster starts and quicker acceleration
  • Better fuel economy and lower emissions
  • Best OEM Iridium spark plug available
  • Original Equipment Manufacturer approved design


What is the difference between Laser Iridium and Iridium IX?

NGK Laser Iridium:

  • OEM style
  • Smallest iridium tip ensuring best durability
  • Longer life plug due to the use of a Platinum Pad
  • Lifespan of 80,000 Miles - 100,000 Miles


NGK Iridium IX:

  • Next best to Laser Iridium
  • Slightly larger Iridium tip than Laser Iridium but still ensures good durability
  • Lacks a platinum Pad; meaning shorter operating life due to oxidization
  • Lifespan of 40,000 Miles - 50,000 Miles
