[OmarLee]

The replacement interval for spark plugs on a Mercedes-Benz GLC260 is every 30,000 kilometers. If you notice a lack of engine power while driving, it's advisable to have them inspected and serviced. Consequences of not replacing spark plugs: The spark plugs in a Mercedes-Benz GLC directly affect the engine's acceleration performance and fuel efficiency. Prolonged lack of maintenance or failure to replace them on time can lead to severe carbon buildup in the engine and abnormal cylinder operation. Function of spark plugs: Commonly known as spark plugs or "fire mouths," their role is to release the high-voltage pulses delivered by the ignition cables, creating an electric spark by ionizing the air between the electrodes to ignite the air-fuel mixture in the cylinder. Main types include: standard spark plugs, extended tip spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs, among others.
