Now many owners have this doubt: When replacing the filter after the warranty, it is too expensive to change the original parts in the 4S shop, and replace them with other brand parts. Is there any problem with the product quality? So the role of automobile oil filter and how to buy it? In fact, the three filters used by car companies are nothing more than the supply of a few big factories, and when we know the brand of the original car, we can buy it by ourselves without having to go back to the 4S shop to accept those pit prices.

Before recognizing the brand of filter, let's review the impact of poor quality filters on vehicles.

1. Inferior air conditioning filters are easy to cause illness in the car and increase harmful substances in the car
The main function of the air conditioner filter is to filter out various particles and toxic gases in the air that passes through the air conditioning ventilation system. To put it in perspective, it is like the "lungs" of the car to breathe, delivering air to the carriage. If you use inferior air conditioning filters, it is equivalent to installing a bad "lung", can not effectively isolate toxic gases in the air, and grade easy to mold and breed bacteria, long-term in such an environment, on their own and family health will cause bad effects.

In general, it is enough to replace the air conditioner filter once a year, if the air dust can shorten the replacement cycle according to the situation.

2. Poor quality oil filter will cause serious engine wear
The function of [oil filter] is to filter out harmful impurities from the oil pan, and to lubricate, cool and clean the moving accessories such as crankshaft, connecting rod, camshaft, supercharger, piston ring and so on with clean oil, thus extending the life of these parts. If the poor quality of the oil filter is selected, the impurities in the oil will enter the engine compartment, and eventually lead to serious engine wear and need to return to the factory for overhaul.

The oil filter usually does not need to be replaced separately, as long as the oil filter is recommended to be replaced together when replacing the oil.

3. Inferior air filter will increase fuel consumption and reduce vehicle power
There are various foreign objects in the atmosphere, such as leaves, dust, sand and so on. If these foreign substances enter the engine combustion chamber, they will increase the wear of the engine, thereby reducing the service life of the engine. [Air filter] is an auto part used to filter the air entering the combustion chamber. If a poor quality air filter is selected, the intake resistance will increase and the engine power will decrease. Or increase fuel consumption, and it is easy to produce carbon deposits.

The service life of the air filter varies according to the local air conditions, but the maximum is not more than 1 year, and the vehicle must be replaced once the air filter when the driving distance is not more than 15,000 kilometers.

4. Poor quality fuel filters will cause the vehicle to fail to start
The function of the fuel filter is to remove solid debris such as iron oxide and dust contained in the fuel to prevent the fuel system from clogging (especially the fuel nozzle). If a poor quality fuel filter is used, the impurities in the fuel can not be effectively filtered, which will lead to oil blockage, and the vehicle will not be able to start due to insufficient fuel pressure.

Different fuel filters have different replacement cycles, and we recommend replacing them every 50,000-70,000 kilometers. If the fuel oil used is not good for a long time, the replacement cycle should be shortened.
