- NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs-and just thin enough to create an accurate and consistent spark
- They represent the ultimate evolution of spark plug technology and performance
- Iridium is the hardest metal used in spark plugs today-six times harder than platinum. This allows for reduced voltage requirement for a spark
- Lower fuel consumption
- Longer life
- Smoother engine running
- Improved ignition efficiency giving enhanced power and acceleration
