178010N060 – Air filter OE number by TOYOTA 178010N040C 178010N040B

Automotive filters are mainly divided into four categories:
According to different filtering functions, it is divided into: oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter, air cabin filter, etc. The engine has three types of filters: air, oil, and fuel, generally called “three filters”, plus an air conditioning filter, commonly known as four filters. They are respectively responsible for the lubrication system, the medium in the combustion system, the engine intake system, and the filtration of the cabin air circulation system.
1. The function of the air filter
In order for the engine to function properly, a large amount of pure air must be drawn in. If the substances harmful to the engine in the air (dust, colloid, aluminum oxide, iron oxide, etc.) are inhaled, the cylinder and piston components will increase the burden, causing abnormal wear, and even mixing with the engine oil, resulting in greater wear , resulting in deterioration of engine performance and shortened life. At the same time, the air filter also has a noise reduction function. The air filter is generally required to be changed every 10,000 kilometers in order to achieve the best use effect.
2. The function of air cabin filter: it is used to filter the air in the car compartment and the air circulation inside and outside the compartment. Remove the air in the compartment or the dust, impurities, smoke odor, pollen, etc. in the air entering the compartment to ensure the health of passengers. At the same time, the air conditioner filter also has the effect of making the windshield difficult to fog. The air cabin filter is generally required to be replaced once every 10,000 kilometers in order to achieve the best effect.
Misunderstanding: Most people think that the filter element works only when the air conditioner is turned on in summer; in fact, it is used to filter the air entering the car all year round. In order to protect your health, don’t ignore the efficacy of this small filter element!
3. Oil filter: As a part of the internal combustion engine, it plays a very important role in the lubrication system. It can filter out impurities such as metal debris, carbon particles, and colloids gradually produced by the engine oil that are produced during the combustion process of the engine and mixed into the oil. These impurities will accelerate the wear of moving parts and easily cause blockage of lubricating oil passages. The oil filter ensures the normal operation of the internal combustion engine, greatly improves the service life of the internal combustion engine, and can also prolong the service life of other parts.
4. Fuel filter: (gasoline filter/gasoline grid/diesel grid) function
The function of the fuel filter is to filter the fuel (gasoline, diesel) required for engine combustion, prevent foreign matter such as dust, metal powder, water organic matter, etc. from the fuel from entering the engine, and prevent engine wear and blockage of the fuel supply system .
