Iridium spark plugs

Iridium spark plugs from NGK are currently the most technically advanced solution. They feature an iridium alloy tip at the center electrode. This point is laser-welded using a special method.

The precious metal iridium is one of the hardest metals in the world. It only melts from 2450 °C and is very resistant to spark erosion. By using this metal, the life of these spark plugs is doubled compared to standard spark plugs.

As a result of this noble metal, the center electrode can also be designed with a thickness of 0.6 mm, i.e. substantially thinner. This measure provides a significant reduction in the necessary ignition voltage and contributes to improving the expansion of the flame front in the combustion chamber.
