More power with NGK Iridium NGK has taken a significant step into the world of high technology with the Iridium IX spark plug. Laboratory tests have shown that the iridium in a spark plug transforms it into a power spark plug. Iridium is thus a high-tech precious metal. It occurs in alloys with other platinum metals in Russia, Colombia, South Africa, and Canada. Its uniqueness: it is as hard as few other precious metals and resistant to most chemicals. The silver-white precious metal, which shimmers in all colors of the rainbow, melts only at 2450 degrees. This valuable precious metal is used wherever special quality is required: in fountain pen nibs, electrodes, in the chemical industry, and in aerospace. NGK utilizes these advantages for the Iridium IX spark plugs. Iridium as the base material of these spark plugs - that is the quantum leap in spark plug research! The secret of the Iridium IX spark plug lies in the laser-welded electrode made of iridium. With its minimal diameter of only 0.6 mm, it concentrates the ignition voltage, thereby improving combustion at all driving stages. This ensures that the engine runs smoothly, and the motorcycle accelerates faster. The high-tech metal iridium maintains the exact distance between the electrodes, preventing misfires.
