These 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.

NGK iridium spark plugs

Apart from the fact that the rear plugs on the 1MZ-FE engine can be a little difficult, it is only the tight area. Any mechanic should be able to easily in an hour. The difference it make over the standard platinum plugs is huge, I removed a near new set platinum plugs to fit the iridium. The extra torque and fuel saving is very noticeable. The engine runs much smoother. I even fitted a set to my GSX1400 Suzuki with the same results. more
