After the air cleaner filter, it can prevent air dust、sand and etc into the engine resulting wear and can protect engine work effectively.
Air filter replacement cycle
If filter element blockage serious, it will lead to higher intaking resistance pressure, decrease engine power, then produce carbon deposition. Usually you have to check the air filter element, Depending on driving traffic, every 5000-10000 kmthat you need replace oil filter again.

Fuel Filter
Fuel filter is acting on the engine combustion systems, filter is string in the throttle body and fuel pumpinto the pipeline between the oil port. The main function of the fuel filter is filtering out  the impurities contained, preventing blockingof the fuel system, reducing the mechanical wear, and then to ensure the enginecan normal operation.
Fuel filter replacement cycle
The fuel filter should be replaced every 20,000 km. If the oil is poor with poor road conditions ,accordingly , the filter need to short the replacement cycle.

Cabin Filter

Cabin filter is also known as "pollen filter" that canwork on filtering impurities in the air conditioning system of the engine to prevent dust, pollen and other impuritiesin the air, pollution caused by the internal air conditioning system, the protection of the people in the car.
