How many kilometers should the Accord air filter be replaced?

According to the car's maintenance manual, the air filter of the Accord should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The position of the car's air filter element is determined by the intake form and the structure of the engine. 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. The dry type is made of paper or organic materials, while the wet type is made of metal wire mesh. The function of the air filter: to filter out particulate impurities in the air, ensuring that enough clean air enters the cylinder, preventing floating dust in the air from being sucked into the engine, which accelerates the wear of the piston group and the cylinder. Air filter: It is a type of filter, also called 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 needs to suck 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 the cylinder. Larger particles entering between the piston and the cylinder can cause severe cylinder scoring, which is particularly serious 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 enough clean air enters the cylinder. Using a dirty air filter while driving will cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several clean air filter components. Its main function is to filter out harmful impurities in the air that is about to enter the cylinder, to reduce early wear of the cylinder, piston, piston ring, valve, and valve seat. Therefore, before the air enters the cylinder, it must first pass through the fine filtration of the air filter. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When checking the air filter, if you find that there is less dust and the blockage is light, you can use high-pressure air to blow it clean from the inside out and continue to use it. A dirty air filter should be replaced in time.
Having driven an Accord for so many years, I generally recommend replacing the air filter between 15,000 to 30,000 kilometers, depending on your driving environment and personal habits. If you frequently drive in congested urban areas with heavy dust or encounter harsh weather conditions, the filter tends to get dirty faster and may need replacement as early as 15,000 kilometers. Conversely, if you mostly drive on highways in less polluted areas, you can stretch it to 30,000 kilometers. I remember one time when I delayed replacing it, the engine noise increased, fuel efficiency dropped, and overall performance was affected. Changing the filter is quite simple—just buy a matching OEM part, and you can do it yourself in about ten minutes, saving both money and hassle. If you find it troublesome, visiting a reputable repair shop is also an option; they can also check for other component-related issues. In short, regular replacement ensures smooth engine breathing, extends the vehicle's lifespan, and reduces long-term maintenance costs.
