【Mrefilter】The air filter hasn't been replaced for two years

If the air filter element has not been replaced for two years, it is likely that it has been clogged. It is recommended to replace it in time. Regarding the replacement time of the air filter, there is no accurate, consistent, and standard answer. Some people say that it is replaced every 10,000 kilometers, and some people say that it is replaced every 20,000 kilometers. In reality, it is necessary to analyze differently according to the actual situation. Under normal conditions, it can be replaced every 20,000 kilometers when driving in a city. If the road conditions are bad, dusty, and the air quality is poor, the replacement time should be shortened, and it is best to replace it every 10,000 kilometers. Correspondingly, if the air quality in the area is good and there is no pollution, the replacement time can be postponed accordingly. The specific replacement time will vary depending on the brand and model. It is recommended to check the maintenance manual (vehicle instruction manual), there will be a detailed introduction on it, and replace it according to the requirements specified in the maintenance manual. You can also check the air filter every time you maintain it. If the air filter element is not particularly dirty, but there is slight sand, dust, etc., you can simply clean it up without replacing it. When cleaning, do not wash with water and blow with an air gun. Be sure to blow gently, usually from the direction the air enters.
