Collection: NGK Iridium IX Spark Plugs (4 plugs set)
What is Iridium IX ?
Iridium is one of the hardest material used in spark plug construction. It is a denser metal allow, 6 x 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 NGK Iridium IX spark plugs have a fine-wire iridium center electrode that requires less voltage to spark. This ensures better and more consistent ignition, leading to improved engine performance.
The fine-wire design of the spark plug enhances the flame kernel formation during combustion. This contributes to more efficient combustion of the air-fuel mixture, resulting in better fuel efficiency.
