1.92 €Iridium spark plugs offer superior durability and performance compared to standard spark plugs. Iridium is an extremely wear-resistant and high-temperature resistant material, which allows for a smaller electrode size and improved ignition of the air/fuel mixture. This results in more efficient combustion, increased power, and reduced emissions.
Symptoms of a faulty spark plug can include: difficulty starting, misfires, reduced power, increased fuel consumption, excessive exhaust smoke, and rough engine running. A visual inspection may reveal signs of wear, corrosion, or carbon deposits on the electrodes. If in doubt, it is advisable to replace the spark plugs.
It is always recommended to use genuine NGK spark plugs, specifically designed for your engine. Using spark plugs from other brands may compromise engine performance and cause damage. If you must use an alternative, carefully verify compatibility and technical specifications.
