NGK, the world leader among candle manufacturers, with Iridium IX has managed to reach a further milestone in technological development. In laboratory tests, si shown that the use of Iridium makes it possible to produce a candle with excellent performance; le main features of Iridium are: · Hardness, higher than other precious metals; Resistance to major chemical agents; · A very high melting point, over 2,450. C. Iridium thus becomes the basic material of a new generation of candles: le NGK Iridium IX. The main advantages of the Iridium IX 1 NGK candle - the best lighter avoids smearing in any driving condition 2 - the particular design of the mass electrode and the central electrode ensures that they are completely eliminated le possible failures of ignition. In addition, by lowering the level of unburned hydrocarbons, le Iridium IX candles protect the catalyst and safeguard the environment 3 - ready and progressive più accelerations that increase driving pleasure 4 - safe ignitions, homogeneous combustion and optimal engine performance are the result of a state-of-the-art technology that reduces fuel consumption 5 - the optimized shape of the electrode reduces the voltage required for ignition
