Iridium – high performance spark plugs by NGK - Simply more power – with iridium
The “secret” of the Iridium IX spark plug is its laser-welded electrode made of iridium. Thanks to its exceptional thin diameter of 0.6 mm it bundles ignition voltage, thus improving combustion at any speed. The engine runs smoothly, the motorcycle accelerates faster. Also, the high-tech metal iridium keeps the distance between the electrodes completely stable, thus preventing the engine from backfiring.
