Iridium Spark Plug

NGK Iridium spark plugs currently represent the highest quality technical solution

They feature an iridium alloy on the centre electrode, which is welded on in a special process using a laser

The precious metal iridium is one of the hardest metals in the world

Its melting point is 2450 °C and is therefore particularly resistant to spark erosion

By using this metal, the service life is doubled on average compared to conventional spark plugs made of nickel
