- The use of iridium alloy dramatically ameliorates the ignition performance.
- 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.
