When does the car air filter need to be replaced

Air filter element I believe that the car friends are very familiar with, maintenance, is often met accessories. As the engine "mask", the main role is to filter the gas into the engine. Provide clean air for engine work, prevent excessive impurities and dust into the engine, greatly reduce engine wear and damage. And the air filter element in the use of a period of time, the impurities in the air and dust will be blocked in the filter element, so the air filter element itself will be very dirty, and dirty air filter, will not play its original role, but also damage the engine.

If the dirty air filter has been used, it will lead to dust and debris in the air and other harmful substances will directly enter the engine cylinder. Will accelerate the engine valve, cylinder liner and piston ring wear, thus affecting the life of the engine. If you do not install the air filter element, although it will make the engine intake more smoothly, but the consequences are unthinkable. And generally in the maintenance of the car, when the air filter is dirty, it is directly washed with high pressure air gun on the air filter. Although it can be very effective to cover the dust impurities on the air filter to blow clean, but often rely on blowing and washing without replacement, the gap in the air filter will become very large. Thus losing the filtering effect, it is recommended to blow and wash twice or so can be replaced, of course, too dirty, do not need to blow and wash, directly replace.

In addition, in the rainy season, if the air filter element is found to be water, it is recommended that the owner immediately turn off, because the air filter element is water, the engine is likely to be water, so as not to occur in the engine water cylinder! And for how long to replace the air filter element, some people say 5,000 kilometers, some people say 10,000 kilometers, in fact, this problem is not an accurate answer. In fact, the replacement of the air filter element is needed to see the usual road conditions and weather to decide, for example, some areas are a lot of dust, big sand this kind, every maintenance should be checked on the air filter element, when necessary, also need to protect a change. And some air quality is better in the city, it is to be able to extend the replacement, after a 10,000 or 20,000 highway to replace it.
