High Heat Rating Plugs for Tuned Engines


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