Don't ask about the quality when buying
Because a few maintenance personnel did not realize the importance of air filters, they only wanted to be cheap, not quality. As a result, after the engine was installed, abnormalities quickly occurred. Especially in the current market, where there are many fake and shoddy products, we need to compare our products with others, carefully choose, and always adhere to the principle of quality first.
2. Disassembly at will during use
The engine must use scientifically based air filters.
However, some drivers arbitrarily remove the air filter and let the engine directly suck in unfiltered air to work. The truck air filter disassembly experiment shows that after the air filter is disassembled, the engine cylinder wear will increase by 8 times, the piston wear will increase by 3 times, and the piston ring wear will increase by 9 times.
3. Maintenance and replacement are not based on reality
In the air filter instruction manual, although mileage or operating hours are specified as maintenance or replacement data. However, in fact, the maintenance and replacement intervals of air filters are also related to environmental factors.
For vehicles that frequently drive in dusty environments, the maintenance or replacement cycle of the air filter should be shortened; For dusty cars, the maintenance or replacement cycle of the air filter is sufficient. Extend appropriately.
In practical work, many drivers and maintenance personnel mechanically follow regulations and do not have the flexibility to grasp different factors such as the environment. They insist on waiting until the mileage reaches the standard and the engine's operating state is significantly abnormal before performing maintenance. It should be noted that if maintenance is carried out at this time, not only the losses already caused cannot be recovered, but also greater harm will be caused. What's more, individual drivers do not even know that the air filter will fail, so they can continue to use it as long as the appearance is not damaged.
