Whether to replace the car air intake grille after it is cracked depends on the situation. If it is not a serious crack, there is no need to replace it. Of course, if the cracks are severe, they must be replaced.

　　The main functions of the air intake grille are:

　　1. The air intake grille injects air to reduce the temperature of the engine and fuel tank when the vehicle is driving. When the car is just started in winter, if the engine fuel tank temperature is not high, and the air is continued to be injected to cool down, the fuel tank temperature will rise more slowly, affecting the effect of the warm air in the car.

　　2. Temperature is one of the important factors affecting engine operating conditions, but vehicles with the highest fuel consumption when the engine is operating optimally and with an active air intake grille should actively adjust the air intake grille angle according to the engine and fuel tank temperatures to reduce engine The cabin dissipates heat outwards.

　　3. In addition, Supapro Auto understands the impact of wind resistance on vehicle fuel consumption. In addition to large-displacement engines, square grilles also affect fuel consumption. On the other hand, the air intake grille of a general vehicle is kept open, and the ventilation resistance increases when driving at high speed. If you choose the right time to close the air intake grille, it will bring a lower ventilation resistance coefficient to the vehicle and reduce fuel consumption.
