First, do not pay attention to quality when purchasing air filters
At present, many car owners do not know the role of air filters very well. They often choose cheaper and poorer quality air filters. These poor air filters have general air filtration capabilities, especially for small suspensions. Particles, poor filtration capacity, and poor physical stability, long-term use will inevitably lead to a decline in the performance of automotive engines, fuel consumption increased significantly.
Second, often remove the car air filter
Some private car owners think that the car air filter does not play much role. 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 and not replaced. As a result, the performance of the car engine may not be affected in a short period of time, but in the long run, the wear of the car engine is very serious.
Third, the maintenance of the car air filter is very rigid, not flexible enough
Most private car owners also know the importance of replacing the car air filter, but when replacing the car air filter, but because of the restrictions of the car maintenance operation instructions, according to the number of mileage provided by the guide, then replace the car filter . However, the degree of pollution in the city is different now, and the corresponding number of suspended particles is different. If it is in a heavily polluted northern city, the replacement and maintenance of the car air filter cannot be easily carried out according to the instructions. The state is obviously abnormal, so the maintenance cycle should be shortened to improve the quality of the car filter. This is the right way to maintain.
