What is one outcome of a clogged air filter?

A clogged air filter restricts the flow of air into the engine, leading to reduced airflow. This is crucial because the engine requires a specific air-to-fuel ratio for optimal combustion. When the air filter is dirty or blocked, it inhibits the engine's ability to draw in the necessary air, which can adversely affect performance.

As a result, the engine may not run as smoothly or efficiently, as it will struggle to achieve the correct mixing of air and fuel for combustion. This can lead to various issues, such as decreased power output, increased emissions, and potential stalling. Maintaining a clean air filter is essential for allowing the engine to operate correctly and efficiently.
