Will There Be Any Impact If the Air Filter Hasn't Been Replaced for Two Years?
2 Answers
If the air filter hasn't been replaced for two years, it is highly likely that clogging has already occurred. It is recommended to replace it promptly. Below is additional information: 1. Replacement interval for air filters: In reality, it should be analyzed based on actual conditions. Under normal urban driving conditions, it can be replaced every 20,000 kilometers. If the usual driving conditions are harsh, with more dust and poor air quality, the replacement interval should be shortened, with the best practice being replacement every 10,000 kilometers. If the air quality in the area is very good with little pollution, the replacement interval can be extended accordingly. 2. Checking the air filter: You can also inspect the air filter during each maintenance service. If the air filter is not particularly dirty, with only minor sand particles or dust, it can be cleaned simply without needing replacement.
Having driven for over twenty years, I've personally experienced the troubles of not changing the air filter for too long. If the filter isn't replaced for two years, the main issue is that it gets clogged with dust and dirt, preventing the engine from getting enough fresh air. As a result, the car becomes sluggish when starting, the throttle feels heavier, and acceleration on the highway becomes difficult. Fuel consumption also increases by about 10% to 15%, leading to significantly higher fuel costs over time. Additionally, impurities entering the engine can wear out cylinder or piston components, causing internal damage that may require expensive engine repairs. This is especially noticeable near construction sites in big cities where air quality is poor, making the filter more prone to clogging. Based on my experience, it's best to replace the filter annually or every 10,000 kilometers—it's not costly and ensures stable performance while extending the vehicle's overall lifespan.
