Iridium Spark Plug, Racing Spark Plug, NGK

Made in Japan

NGK IRIWAY spark plugs, like the NGK Iridium IX, have an Iridium center electrode of 0.6mm diameter offering performances exceeding traditional spark plugs. The ground electrode of Iridium NGK Iriway is tapered cut to provide a better flame spread generated by combustion, raising compressions and ensuring a cleaner burning.
