NGK PREMIUM CLASS LASER IRIDIUM SPARK PLUG

NGK Laser Iridium Spark Plug series provides superior ignitability and long service life. The smallest tip diameter Iridium or Platinum surface ensures slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency, and lower emissions.

Features and Benefits:
  • Ultimate evolution of spark plug technology and performance
  • Reduces the voltage requirement for spark which allows for a brighter and stronger spark from the existing ignition system
  • Iridium tip fine wire center electrode is both stronger and harder than Platinum, while the Platinum tip ground electrode further contributes toward the extreme longevity of the plug
  • Special design firing end construction
  • Double fine electrodes
  • Laser welded tips
Specifications:
  • Copper electrode core material
  • Iridium electrode tip material
