There are several types of filters in a vehicle, but two of the most common are the air filter and the oil filter.
Air filter: The air filter is an important component of the engine's air intake system. It filters out dirt, dust, and other contaminants from the air before it enters the engine. A clogged air filter can reduce engine performance and fuel efficiency, and can even cause damage to the engine over time. It is important to replace the air filter at regular intervals to ensure that it is functioning properly.
Oil filter: The oil filter is responsible for removing contaminants from the engine oil, such as dirt, metal particles, and sludge. A clogged oil filter can reduce engine performance, and can cause damage to the engine over time. It is important to replace the oil filter at regular intervals, along with regular oil changes, to ensure that the engine is running smoothly and efficiently.
Other common filters in a vehicle include the cabin air filter, which filters out pollutants and allergens from the air inside the cabin, and the fuel filter, which filters out impurities from the fuel before it reaches the engine.
