Iridium spark plug - MR9DI-7

NGK Iridium spark plugs currently represent the highest quality technical solution
Feature an iridium alloy on the central electrode, welded using a special laser process.
The precious metal iridium is one of the hardest metals in the world
Its melting point is 2,450 °C, making it particularly resistant to spark erosion.
Using this metal doubles the average service life compared to conventional nickel spark plugs.
