How often does the air filter change?
The air cleaner is what we often say "air filter" for air filter is a very basic maintenance project. Nature is not the same for different car replacement cycle, so no one is absolute standard, because it depends on the amount of suction air filter such as dust and impurities. The same is a the air cleaner, in a long running on the highway vehicle,
Of course, the vehicle running time or mileage, the only reference value, the decisive factor of whether you need to replace the air filter is whether it has been unable to get enough air through the air filter. To ensure filter out impurities in the air, while allowing enough air into the engine.
it can use 30 thousand kilometers or even longer before a replacement; and for a total shuttle between rural and off-road vehicles, it may be replaced within two months. Of course, these two kinds of circumstances are more extreme, for ordinary vehicles in the city, every year or every 2 kilometers after the replacement of a air filter is more appropriate.
There is a need to explain, in fact the air cleaner after a period of time are higher than the efficiency of the new air cleaner. This is because the air filter has the adsorption of impurities can help it to capture more tiny dust. Eventually the air cleaner will due to the accumulation of too much dust and the influence to the engine the operation of the vehicle will appear. When the fuel economy, power and emission gradually worsened, until you get a new air cleaner.
