NGK Iridium Spark Plug BKR6EIX 4PC/SET

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 significantly stronger than any metal used in spark plugs today. It's the hardest metal used (in fact, iridium is 6 times harder than platinum), which has allowed NGK engineers to reduce the voltage requirement for a spark.

• Fine wire Iridium center electrode ensures high durability and a consistently stable spark
• Iridium alloy has an extremely high melting point, perfect for today's high-performance engines
• Trivalent metal plating has superior anti-corrosion and anti-seizing properties
• Special taper-cut ground electrode shape to allow for more area for flame expansion
