Most junior car owners will replace air-conditioning filters and air filters in 4S shops. Although the quality can be guaranteed, they need to pay higher parts costs and working hours. In fact, in the four filters, the replacement of air filters and air conditioning filters is not difficult, and the owner can still do it himself. In addition, when the oil filter and fuel filter are replaced, since most models need to be lifted, we do not recommend replacing them by ourselves.

Air filter function: The air filter is installed at the intake port of the engine. It can effectively filter the dust and impurities in the air and greatly increase the purity of the air entering the combustion chamber, thereby ensuring full fuel combustion.

Price: The air price of general models is between 50 and 100 yuan, while that of a few special models, such as Jaguar, Mercedes-Benz and BMW, is above 100 yuan. The price of auxiliary factory parts is generally 1/3~1/4 of the price of main factory parts, and only 20 or 30 yuan at most.

However, the quality of the auxiliary parts is poor, and the rubber ring is easy to break, which can easily cause oil leakage, which directly affects the operation of the engine and causes wear. It is not recommended to use.

The gasoline grid price of most economic models is between 50 and 100 yuan, and the gasoline grid price of a few special models is between 100 and 200 yuan. The gasoline price of medium and high-grade cars is above 100 yuan, with little overall difference. Some auxiliary factory parts or miscellaneous brand gasoline grid are easy to cause oil leakage, which may cause spontaneous combustion or even explosion. It is quite dangerous for the body and the person and is not recommended.
