Where is the air intake of the Focus located?

[DeArya]

The air intake of the Focus is located in the engine compartment. Open the hood, and the position of the air filter is where the car's air intake is. Air intake blockage: If the air intake is blocked, the air intake volume will be uneven, leading to different fuel injection amounts for each cylinder, resulting in varying torque output from each cylinder and causing engine vibration. Air intake cleaning: Currently, the no-disassembly cleaning method is commonly used. While the engine is running, combustible cleaning agents are injected into the intake pipeline, which can remove carbon deposits to a certain extent. However, due to the long intake pipeline and varying temperatures at different parts, the form and nature of carbon deposits differ, making it difficult to completely clean with a single cleaning agent.
