NGK: the World Leader
As the leading OE supplier of ignition parts for the major automobile manufacturers across the world, no wonder NGK is considered as the World Leader of Spark Plugs!
Harnessing the natural properties of the metal Iridium, NGK has created one of the finest spark plugs available. Iridium IX Spark Plugs require less voltage to spark, burns fuel more efficiently, sparks at leaner air/fuel mixtures, and delivers higher horsepower and better gas mileage. Spark plugs are priced and sold individually.
