NGK has taken a big step into the world of high technology with the Iridium IX spark plug.

Lab tests have shown that the iridium in a spark plug creates 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 special feature: it is harder than almost any other precious metal and resistant to most chemicals. The silver-white precious metal, which shimmers in all the 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 - this is the quantum leap in spark plug research! The new center electrode with its only 0.6 mm thick iridium tip.

More power through iridium. The secret of the Iridium IX spark plug lies in the laser-welded electrode made of iridium. With its minimal diameter of just 0.6 mm, it concentrates the ignition voltage, thereby improving combustion in all driving conditions. This allows the engine to run absolutely smoothly, and the motorcycle accelerates faster. The high-tech metal iridium maintains the exact distance between the electrodes. This prevents misfires.
