Spark plug -NGK MR- Laser Iridium Premium PMR9B - APRILIA Scarabeo Light 125 - 200 (ZD4RBG00, ZD4RBH00, ZD4RBL00, ZD4RBM00)

NGK Iridium spark plugs currently represent the highest quality technical solution. They feature an iridium alloy on the center 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 it 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.
