Description:

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. Iridium IX delivers the performance and durability to meet the demands and expectations of those who expect nothing but the best. from the best. 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. Its 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. Since 1936 NGK has lead the industry in technology, innovation and world class design of its entire product line. You can depend on NGK for quality and reliability. Features: Fine Iridium tip ensures high durability and a consistently stable spark Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties Iridium alloy has extremely high melting point, perfect for todays high-tech, high-performance engines Outstanding acceleration, high fuel efficiency and durability Each Order Contains (2) Two Spark Plugs.
