The design of the ultra-fine center electrode is designed not too thin to ensure maximum durability and life of the spark plug and not too thick for an accurate and consistent spark. NGK Iridium IX spark plugs represent the ultimate evolution of spark plug technology and performance. Iridium is significantly stronger than any metal used in spark plugs today. It's also the hardest metal used (in fact, iridium is 6 times harder than platinum) which has allowed NGK engineers to design an ultrafine center electrode reducing the voltage requirement for spark.
