If an air inlet grille fails, it may cause a decrease in vehicle performance or other issues. The common symptoms are as follows:

1. Degradation in engine performance

Weak acceleration ability: An obstruction in the air inlet grille can limit air flow, and prevent the engine from receiving sufficient air, thereby affecting acceleration performance.

Unstable operation at idle speed: With insufficient air inflow, the engine may experience instability during operation at idle speed.

2. The fault indicator is on

The engine fault indicator on the dashboard lights up, or the message "please check air intake system" appears.

3. Overheated engine

A damaged or obstructed air inlet grille can affect the engine's heat dissipation ability, and may result in excessively high engine temperature.

4. Louder wind noise, decreased range, and increased fuel consumption

During drives at high speed, a failed air inlet grille may cause significantly louder wind noise and higher fuel consumption of gasoline vehicles or shorter range of electric vehicles.

5. Abnormal sound

If the air inlet grille is damaged or its fasteners become loose, changes in air flow may cause abnormal squeaking sounds or other noises.

6. Physical damage

Check if there are any visible fracture, deformation, or misalignment on the blades of the air inlet grille, which can all directly affect air flow direction, reduce heat dissipation efficiency, or even cause flying stones to penetrate the radiator in severe cases.

Advantages of DPA air inlet grille:

1. OE control motor is adopted for DPA air inlet grille, requiring no decoding, and ensuring precise matching.

2. The blades are produced using high-precision models of the same size, leading to smooth blade opening and closing and eliminating noise.
