The filter is mainly used to filter particles, impurities, and moisture entering the engine system. Reasonable selection of high-performance and legitimate brand filters is a measure for users to protect filter replacement, reduce equipment maintenance costs, and extend the service life of the system.  

Hazards of poor quality filters:
Insufficient rated flow leads to long-term overload of the filter and short service life.
The filter paper has a large pore size, poor uniformity, and low filtration efficiency, resulting in early wear of the common rail system.
Water separation failure, corrosion of common rail components, poor oil resistance of adhesive, and weak adhesion, resulting in short circuit of the filter and inability to remove impurities, shortening the service life of the common rail system.
The rubber components of the internal sealing ring of the filter are not oil resistant, resulting in sealing failure, short circuit formation, and inability to filter out impurities, resulting in early wear of the common rail system.
The functions of the fuel filter heating and fuel water separation electrical connectors are malfunctioning and the circuit is damaged. The fuel filter heating is malfunctioning, and the system performance and starting at low temperatures are affected.
The impact of inferior filters on the engine is implicit and may not be immediately detected, but it is too late to erupt when the damage accumulates to a certain extent. 
The measure of filter quality is not only the lifespan of the filter, but also the filtration efficiency of the filter. If a filter with low filtration efficiency is used, even if it is replaced frequently, it does not matter. Due to the presence of water in diesel, it is important to regularly drain water from the filter during use while maintaining the regular filter.
Engine lubricating oil is constantly contaminated by metal shavings, dust in the air, and carbon deposits during use. The heavy impurities settle at the bottom of the oil pan, while the light impurities enter the friction surfaces with the lubricating oil, causing early wear of the components. The function of an oil filter is to filter lubricating oil through the filter to remove dirt. After a certain period of use, a lot of dirt will adhere to the filter, so the filter should be replaced regularly. Generally speaking, the oil filter and oil should be replaced simultaneously. This is beneficial for extending the service life of the engine.
Use an oil filter wrench or appropriate tool to remove the filter to prevent damage to the threads at the connection. Check and clean the installation surface of the oil filter, otherwise oil leakage may occur after installation, resulting in insufficient fuel supply. When installing the oil filter, a layer of oil should be applied to the surface of the sealing ring to ensure reliable sealing and prevent damage to the sealing ring.
Maintaining the cleanliness of the filter is something that any product needs to pay attention to. Nowadays, filters mostly use paper filter elements, and the outer shell is sealed with relatively hard plastic, making it a consumable item. Blockage in the filter results in poor oil flow, resulting in an increase in the internal oil temperature of the filter. So, we can observe the internal oil rise from the casing to determine whether the filter is blocked.
