What happens if the air filter is not replaced for 2 years?
2 Answers
The consequences of not replacing the air filter for 2 years are as follows: 1. It will affect the engine's air intake, leading to a lack of power during acceleration; 2. The engine will experience increased wear and carbon buildup, shortening its lifespan; 3. The phenomenon of "cylinder scoring" may occur. Here is an introduction to the car air filter: 1. The general replacement cycle for an air filter is 10,000 to 20,000 kilometers, which is heavily influenced by driving conditions. If the environment is poor, it needs to be replaced earlier. If the air filter is replaced after 30,000 to 40,000 kilometers, it mainly depends on the condition of the air filter. It is best not to go too long without replacement and to replace it within the specified time. 2. When installing a new air filter, pay attention to the correct orientation. There is a protruding plastic tab on the lower right side of the air filter to prevent incorrect installation. To ensure proper installation, the plastic tab must be secured into the slot of the filter housing.
The air filter in my previous car hadn't been replaced for two years, and the car started running poorly. When accelerating, the engine seemed to gasp, and it took a long time to respond after stepping on the gas pedal. Fuel consumption also skyrocketed, costing me at least an extra 150 yuan a month on gas. Later, during maintenance, the mechanic said the filter was clogged with dust, preventing air from entering and causing incomplete combustion, which even damaged the cylinders. The repair cost nearly 2,000 yuan. This thing mainly filters out impurities from outside the car, and improper maintenance can affect the engine's lifespan. It's recommended to replace it every 10,000 kilometers or once a year. Checking it myself is simple—just pull it out to see if it's dirty or black, then replace it with a new one. Don't follow my example and wait until the problem worsens—that's truly a case of being penny-wise and pound-foolish.
