Spark Plugs with center electrode made with Iridium alloy, it is one of the hardest material used in spark plug construction. It is a denser metal allow, 6 x more dense compare to platinum. It is one of the hardest materials used in spark plug construction. This hardness helps in resisting electrode erosion and extends the overall life span of the spark plug.

The fine-wire iridium center electrode that requires less voltage to spark. This ensures better and more consistent ignition, leading to improved engine performance. This contributes to more efficient combustion of the air-fuel mixture, resulting in better fuel efficiency.
