Optimal ignition performance: The laser-welded iridium centre electrode has a diameter of only 0.6 mm. This keeps the ignition voltage requirement low and ensures a powerful ignition spark. Long life: Thanks to the precious metal, the Iridium IX spark plug lasts up to twice as long as a standard nickel spark plug and, due to this durability, saves money and installation and removal time. Full performance over the entire service life: With standard spark plugs, the distance between the electrodes increases over time due to burn-off. The quality of the ignition is impaired and misfiring occurs. With Iridium spark plugs, the electrode gap remains almost constant over the entire service life. Notes: please read the general installation instructions before installing! Delivery includes: 1x NGK spark plug ILNAR8B7G Iridium IX
