What are the consequences of not replacing the car's air filter?

[AshleyLee]

The hazards of not replacing the air filter for a long time: 1. Accelerated engine wear and carbon deposits: It will accelerate engine wear and carbon deposits. If the vehicle is operated without an air filter, dust will directly enter the cylinder and mix with oil and gas for combustion. In this case, the degree of cylinder wear will be eight times that of a vehicle equipped with an air filter, three times the piston wear, and nine times the piston ring wear. 2. Dirty engine intake tract: Long-term use of a damaged air filter will not only allow dust to enter the engine but also invade the engine's intake tract, causing it to become dirty. 3. Decreased filtration efficiency: When the air filter is not too dirty, an air gun can be used to blow it clean. When blowing, pay attention to blowing from the inside to the outside. However, most air filters are made of coarse filtration and low wind resistance materials. During driving, the filter forms resistance to the airflow. When the dust accumulation exceeds a certain value, the filter resistance will increase, and the filtration efficiency will decrease.
