NGK BR8ECMIX Iridium IX Spark Plug HASAN 390 RR 4T 15-21NGK Iridium Spark Plugs 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 worlds hardest metals, the precious metal iridium starts melting at a temperature of 2450c and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark
