Iridium is a light colored, precious metal that is among the densest materials on earth. It's natural properties make it a perfect candidate to be used in a NGK spark plug. Iridium Plugs require less voltage to spark and deliver increased burn efficiency, spark at leaner air/fuel mixture, produce better gas mileage and higher horsepower.
