Car and motorbike manufacturers, dealers and workshops have been relying on the ignition specialist's expertise for decades. NGK Laser Iridium spark plugs are first-class technology of the highest calibre! The precious metal means that the centre electrode of the spark plug can be kept much narrower, allowing the petrol-air mixture to flow more easily between the centre and ground electrodes and therefore be better ignited. The result: Significantly improved cold start behaviour and more efficient combustion than with conventional spark plugs, the fuel is optimally utilised. The advantages: Improved ignition behaviour, optimised starting behaviour and smoother running – with lower fuel consumption and reduced environmental impact. An investment that pays off! In both motorsport and everyday use, the high-performance metal iridium ensures top performance. Laser Iridium spark plugs provide the ideal ignition for modern engines. The most important car manufacturers rely on this technology, which is also available to the aftermarket. Longer service life: The use of the precious metal extends the service life of the spark plug compared to standard spark plugs. Optimised starting behaviour: The laser-welded, ultra-fine iridium centre electrode ensures perfect ignition performance and promotes the spread of the flame front in the combustion chamber. Economical in consumption: The excellent ignition capacity contributes to more efficient engine performance, reduces fuel consumption and environmental pollution. Note: Please observe the general installation instructions before installation! Review: Smooth running restored. - Honda civic, 2009, 1.8 100k on the clock. After the new plugs went in the cars runs almost like new. Torque and smoothness restored. No need for any anti-seize NGK have been putting a special coating on the threads for many years.
