NGK Iridium Spark Plug BPR5EIXNGK
Iridium spark plugs Iridium spark plugs from NGK currently represent the highest-quality technological solution. They have an iridium-alloy tip on the middle electrode. It is welded on in a special process using a laser.The precious metal iridium is one of the world's hardest metals. It starts melting at a temperature of 2450 °C and is very resistant to spark erosion. Through its use, the service life is doubled on average in comparison to standard spark plugs. In addition, the precious metal allows the middle electrode to be designed significantly thinner, with a thickness of 0.6 mm. These measures reduce the ignition voltage requirement considerably and contribute to improving the spread of the flame front in the combustion chamber.
