What are the essential maintenance items for a car at 20,000 kilometers?

[EvaFitz]

At 20,000 kilometers, a car requires maintenance on the engine oil, oil filter, air filter, brake pads, spark plugs, among others. In addition to these, there are several other items to consider: cleaning the throttle body and fuel injectors, performing a tire rotation and wheel balancing, replacing the cabin air filter, and cleaning the catalytic converter. Here is some additional information: Spark plugs: They are responsible for introducing high-voltage current into the cylinder in a gasoline engine's ignition system to generate a spark that ignites the combustible air-fuel mixture. If the vehicle experiences a lack of power, the spark plugs should be inspected. Additionally, during the 20,000-kilometer maintenance, it is important to check the thickness of the brake pads. If they are excessively worn, the brake pads should be replaced.
