How many kinds of Mercedes-Benz air intake grilles are there?

There are three kinds of Mercedes-Benz air intake grilles, one for the normal version, one for the sports version and one for the hybrid version: 1. The air intake grille is used to protect the components in the water tank and engine compartment from foreign objects; 2. The main function of the front grille is heat dissipation and air intake. If the water temperature of the engine radiator is too high, the fan will automatically start the auxiliary heat dissipation only if the natural air intake can not fully dissipate the heat; 3. When the vehicle is running, the air flows backward, and the direction of the fan airflow is also backward. After heat dissipation, the rising temperature airflow flows back to the car from the position behind the hood near the windshield, and the heat is discharged.
