What material is the original spark plug of the Skoda Kodiaq?

The original spark plug of the Skoda Kodiaq is made of NGK platinum material. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high voltage into the combustion chamber and causes it to jump across the electrode gap, generating a spark to ignite the combustible air-fuel mixture in the cylinder. Under high voltage, the air between the spark plug's center electrode and the side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. A discharge channel forms in the gap, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with the heat expansion, a "crackling" sound is also produced. The temperature of this electrical spark can reach as high as 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.
