True and false auto parts for the non-auto repair industry, it is really difficult to distinguish the true and false! The appearance of inferior products is almost the same as the real, many owners in order to save money, but this caused damage to other parts of the car, but caused unnecessary losses!

Hazards of poor quality oil filters

1. The filter paper of inferior oil filter is poor in material, and it is difficult to reach the filter effect required by automobile engine. Moreover, the filter area is smaller than that of the original oil filter.

2. Low-quality oil filters often do not have by-pass valves. Once the filters are blocked, the engine will not be able to get enough oil lubrication. In serious cases, the engine will jump teeth, burn tiles, or even scrap.

3. The inferior oil filter has no function of inhibiting oil reflux after flameout. The mechanical wear of the engine during cold start increases and the engine life is reduced.

4. The rubber sealing ring of inferior oil filter is poor in material and deformed under high temperature and high pressure, resulting in ineffective sealing and oil leakage.

Hazards of poor quality gasoline filters

1. The filter element used in the inferior gasoline filter is of poor material, poor filtering effect, impurities in gasoline are easy to plug the nozzle, resulting in increased fuel consumption, engine jitter, and serious damage to the nozzle.

2, poor gasoline filter will make the oil supply pressure unstable, oil pressure is too low or too high. Low oil pressure engine is difficult to start, vehicle power is insufficient, high oil pressure will make gasoline combustion incomplete, high fuel consumption and easy to damage the ternary catalytic converter and oxygen sensor.

3. The filter element of the inferior gasoline filter is not resistant to gasoline corrosion. If the filter element falls off and blocks the oil passage, the engine will not start and the vehicle will break down, thus causing damage to the engine.

Hazards of poor air conditioning filters

1. The filter material of the inferior air-conditioner filter is hard and often adopts single-layer filtration, which is easy to be blocked and has poor air permeability.

2. The bonding materials used in the filters of poor quality air conditioners are poor, easy to crack and damage, short service life; the distribution of activated carbon is uneven, and it is unable to effectively filter toxic gases;

3. Poor air-conditioning filters filter dust and bad odor removal effect, harmful gases in the air into the car, causing damage to the human respiratory system, physical health is affected;

4, poor air conditioning filters easily cause dust and foreign matter to accumulate on evaporator, causing odor in the car.
