1. Don't pay attention to quality when buying air filter

Although many car owners will choose 4S shops when replacing air filters, but with in-depth understanding of car structure, it is very simple to replace car filters by themselves, but whether it is in 4S shops or by themselves, they will It involves buying a new air filter. However, many car owners are not very correct about the role of air filters. They often choose cheap and poor quality air filters. These poor quality air filters have average air filtration capabilities, especially for small ones. Suspended particles, poor filtering ability, and poor physical stability, and long-term use will inevitably lead to a decline in automobile engine performance and a substantial increase in fuel consumption. For example, the Manhu air filter in the figure below is clearer than other air filters in terms of volume and appearance. The double-layer structure is very obvious, and the filtering capacity is almost double that of other brands.

2. Frequently removed when using the car air filter

Some private car owners think that the car air filter is not very useful. After a new car has been used for a period of time, it is found that the air filter has been completely blocked. At this time, the air filter is simply removed without replacing it. The result of this may not affect the performance of the car engine in a short time, but in the long run, the wear and tear on the car engine is very serious. There are data showing that without car air filters, the wear rate of car engine cylinders will exceed eight times, the wear rate of pistons will exceed 3 times, and the wear rate of piston rings will exceed 9 times.

3. The maintenance of car air filter is very rigid and not flexible enough

Most private car owners also know the importance of replacing the car's air filter. However, when replacing the car's air filter, they are restricted by the car maintenance operation guide. After the mileage provided by the guide, replace the car filter. . But nowadays, the pollution degree of cities is different, and the corresponding amount of suspended particles is different. If the pollution degree is heavy in northern cities, the replacement and maintenance of the car air filter can not be simply carried out according to the instructions. The condition is obviously abnormal, so the maintenance period should be shortened to improve the quality of the car filter. This is the correct way of maintenance.
