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
