NGK Iridium Spark Plug XT-660

The secret of the new NGK Iridum IX spark plug is the laser-welded electrode made of Iridium. Thanks to her "minimal" diameter of only 0,6mm it concentrates the ignition voltage. This improves the combustion in all drives. Thereby the engine runs absolutely round, the motorbike speeds up faster. The high-tech metal iridium ensures the exact spacing between the electrodes. This prevents ignition misfire.

The XT gets a notably softer engine operation, the gas acceptance is improved. Further, the Iridium spark plugs' durability is twice as long as that of "normal" copper spark plugs.
