NGK Spark plug SILKGR9A7ES Iridium NGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.   Diameter : M12 Spanner size : 16 Spark Plug : 1 - Earthed Electrode Thread Size : 26.5
