Provide clean air for engine work, prevent excessive impurities and dust from entering the engine, and greatly reduce engine wear and damage. After using the air filter element for a period of time, the impurities and dust in the air will be blocked on the filter element, so the air filter element itself will be very dirty, and the dirty air filter element will not play its original role, but also damage the engine.

If the dirty air filter element has been used all the time, it will cause harmful substances such as dust and debris in the air to enter the engine cylinder directly. It will accelerate the wear of engine valves, cylinder liners and piston rings, thus affecting the service life of the engine. If the air filter element is not installed, the air intake of the engine will be smoother, but the consequences will be unimaginable.

Generally, when maintaining your car, when the air filter element is dirty, you directly use a high-pressure air gun to purge the air filter element. Although it can effectively purge the dust and impurities covered on the air filter element, the gap in the air filter element will become large if it is often purged without replacement. Thus, the filtration function will be lost. It is recommended to purge twice and replace it. Of course, if it is too dirty, you don't need to purge it and replace it directly.

In addition, in rainy seasons, if water is found in the air filter element, it is recommended that the owner turn off the engine immediately, because once the air filter element enters the water, there is likely to be water in the engine, so as to prevent the engine from entering the water and jacking the cylinder!
