NGK Iridium Spark Plug MR8BI-8 for 50cc 4T 3V Engines

NGK Iridium spark plugs currently represent the highest quality technical solution. They feature an iridium alloy on the center electrode, laser-welded in a special process. Iridium is one of the hardest metals in the world, with a melting point of 2450 °C, making it especially resistant to spark erosion. Compared to standard nickel spark plugs, their service life is typically doubled thanks to this precious metal.
