Service life)up to 150,000 kmNGK Laser Spark Plugs Iridium is a technological solution of the highest quality. The use of iridium not only improved performance but also doubled the life of conventional nickel spark plugs.
Design features of iridium spark plugs: Iridium alloy tip on the middle electrode, laser-welded using a special technology.
Ultra-thin electrode (0.6 mm) that significantly reduces the ignition voltage and improves the spread of the fire front in the combustion chamber.
Due to the special shape of the central electrode, carbon deposits are burned from the edge of the insulator, which helps to maintain the insulating properties and prevents erroneous ignition.
Advantages of NGK Iridium spark plugsIridium resistance to high temperatures, pressure and electroerosionStable sparkingImproved ignition of the fuel-air mixtureEfficient combustionEconomical fuel consumptionIncreased spark plug life up to 100,000km
