NGK Iridium Spark Plug – Part Number: SILZKBR8D8S

NGK iridium spark plugs feature an iridium alloy on the centre electrode, welded on with a laser – one of the world's hardest metals, with a melting point of 2450°C, giving very high resistance to spark erosion and, on average, double the service life of a standard nickel spark plug.
