How many kilometers should the Toyota Levin air filter be replaced?

According to the car's maintenance manual, the Levin's air filter is generally replaced every 40,000 kilometers or every other maintenance interval. If the driving environment is poor, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The location of the car's air filter element is determined by the intake form and the engine's structure. It is usually located in the air filter on the engine intake pipe. There are two types of air filters in cars: dry and wet. Dry filters are made of paper or organic materials, while wet filters are made of metal mesh. The function of the air filter is to filter out particulate impurities in the air, ensuring that clean air enters the cylinder and preventing floating dust from being sucked into the engine, which accelerates the wear of the piston group and cylinder. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. A dirty air cleaner: Using an excessively dirty air cleaner while driving can cause insufficient engine intake, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car's air cleaner must be kept clean. The car's air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities in the air before it enters the cylinder to reduce early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must first pass through the fine filtration of the air cleaner. Notes about the air filter: An air cleaner that has been in use for some time is more efficient than a new one. This is because the impurities already adsorbed by the air cleaner help it capture more tiny dust particles. An air cleaner that looks dirty does not necessarily mean it can no longer function properly. The driving time or mileage of the vehicle is only a reference value. Whether it needs to be replaced depends on the actual situation, such as whether it can no longer allow sufficient air to pass through. The air cleaner must ensure that it filters out impurities in the air while allowing enough air to enter the engine.
I've got plenty of experience changing air filters on my Toyota Levin. Generally, it's recommended to inspect it every 10,000 to 15,000 kilometers. If it looks dirty, replace it early - don't delay beyond 15,000 km. In urban areas with less dust, you can wait slightly longer. But if you're driving in rural or heavily polluted areas where there's more dust, a clogged air intake will restrict engine breathing, making acceleration sluggish and increasing fuel consumption. A new filter only costs a few dozen yuan to save you trouble. Personally, I change mine every 10,000 km - just pop open the engine cover box to check the color; if it's black, it must be replaced. This keeps the engine breathing smoothly for optimal performance. Remember not to exceed the manual's maximum limit of 20,000 km, as prolonged neglect could allow debris buildup to potentially damage the engine. It's best handled during routine maintenance.
