Today, the Automotive Components business has expanded to become the world’s top global manufacturer of OE and Aftermarket ignition and vehicle electronics parts. Benefit from our decades of know-how and outstanding expertise in Original Equipment and spare parts business. We promise: Under our new company name Niterra (formerly NGK SPARK PLUG), we continue to be the reliable partner at your side today and tomorrow. Ultimate Engine Combustion NGK spark plugs deliver smooth engine starting and running, general engine performance and efficiency as well as the reduction of harmful emissions. Niterra is the world's leading manufacturer of spark plugs for original equipment and the aftermarket. 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!
