Heavy-duty filter tips
Special attention needs to be paid to the quality of the air filter. Long-term use of inexpensive, poor quality air filters can result in degraded car engine performance. Fuel consumption has risen sharply. After using the new car for a period of time, if the air filter is completely blocked, be sure to replace it in time. Do not remove the car air filter from time to time. The maintenance of the car air filter is very rigid and not flexible enough. In general, air conditioning filters are replaced once a year. If the air dust is large, the replacement cycle can be shortened.
