The Iridium Spark Plug produces much more complete combustion, which delivers more power and response to the driver. It helps to draw out the full potential of an engine. The thermo edge set at the top of the insulator limits the deposition of carbon, which otherwise can reduce firing performance and cause poor idling. This also increases reliability and durability.
