Car and motorbike manufacturers, dealers and workshops have been relying on the ignition specialist's expertise for decades. With NGK high-performance spark plugs, the Iridium top technology is also available for older vehicle and motorbike models! Using the precious metal iridium, the centre electrode of the spark plug can be kept much narrower, allowing the petrol-air mixture to flow more easily between the centre electrode and the earth electrode and to be ignited more easily. The result: fewer misfires than with conventional spark plugs, the fuel is optimally utilised. An investment that pays off! The advantages: Improved ignition behaviour, optimised cold start behaviour and smoother running – with lower fuel consumption at the same time. In motorsport as in everyday use, the high-performance metal iridium ensures absolute top performance. This is why more and more manufacturers are installing Iridium spark plugs in series production. Excellent starting behaviour: The laser-welded iridium centre electrode (Ø 0.6 mm) minimises the ignition voltage requirement for optimum ignition. Special technology against sooting: Spark plugs with an extremely thin, laser-welded centre electrode and a special technology against ignition problems caused by sooting. Note: Please observe the general installation instructions before installation! Review: Perfect - Decently improved idling and better file consumption on my Wife’s BN125 Benelli..
