Why are NGK spark plugs superior?
NGK spark plugs are superior for several reasons: 1. Reduction in Heating and Fouling. It has a centre electrode with copper deeply inserted in the tip to quickly dissipate large amounts of heat. This makes a spark plug with an “ultra wide heat range” that resists both heating and fouling. NGK Spark Plugs cover a wider range of temperatures than that of standard plugs. When the thermal characteristics of spark plugs with and without copper cores are compared, spark plugs with copper cores prove to be superior in heat and fouling resistance and provide a wider thermal operating range. 2. Incorporates an insulator made of state-of-the art high-alumina ceramics.
