The air filter element will shake if it is dirty. The air filter is designed to protect the engine and reduce wear. Generally, it is replaced at about 10,000 kilometers. If it is not replaced in time, insufficient air intake will occur, causing low idle speed and causing engine jitter. It can be solved by replacing the filter element.

What happens when the air filter element is dirty is analyzed as follows:
1. If the air filter element is too dirty, it will first cause the engine's air intake to be blocked. When the vehicle needs to speed up, due to the insufficient intake air volume, the fuel injection volume of the vehicle does not increase correspondingly under the detection of the intake pressure sensor, etc., which leads to the obstacle of the power output. If impurities enter the cylinder, it will aggravate the formation of carbon deposits and bring greater wear to the cylinder and piston components;
2. Since the air-conditioning filter element is used to prevent impurities such as dust and pollen from entering the car, if the air-conditioning filter element is too dirty, it will directly affect the health of the people in the car. Falling leaves in summer and rainy environments can easily cause bacteria to grow at the air-conditioning filter element. The air-conditioning filter is generally required to be replaced once 10,000 kilometers, and it is also necessary to clean up in advance after experiencing heavy rain;
3. Simply put, the air filter element is equivalent to the lungs of the engine, and the importance of the human lungs is self-evident. Therefore, the air filter element has a great influence on the engine, and the car owner should pay special attention to the maintenance of the air filter element, and it should be cleaned and replaced in time. For the health of you and your family, and for the health of your car.
