Automotive three filters refer to air filters, oil filters and gasoline filters. Their function, as the name suggests, is to filter and purify any gas and liquid entering the car engine, thereby protecting the engine and improving the efficiency of the engine.

The main function of the air filter element is to filter the air entering the engine; while the gasoline filter element is to filter the gasoline to ensure the fuel is clean and prevent the generation of impurities; the oil filter element is to filter the oil. If it is maintenance, these three must be replaced. 

Air filter: It is a device to remove dust in the air. When the engine is working, if the inhaled air contains dust and other impurities, after entering the engine, the combustion chamber in the cylinder will reflect the combustion efficiency, so an air filter must be installed.

Gasoline filter element: The main function is to filter impurities in the gasoline. If the gasoline is too dirty or clogged, it will cause problems such as the engine cannot be lifted up and the car is difficult to start. Sometimes it takes 2 to 5 times to strike. The engine is generally a one-time non-removable and washable paper filter element, and the replacement cycle is generally 10,000 kilometers.

Oil filter element: It is also an oil filter. The function of the oil filter is to filter out the sundries, colloids and moisture in the oil, in order to make the engine work more stable and cool.
