What is the impact of a clogged air filter on a vehicle?

A clogged air filter significantly restricts the airflow into the engine, leading to a reduction in the amount of air that can mix with the fuel for combustion. This imbalance results in a decrease in engine performance, as the engine struggles to operate efficiently with insufficient air supply.

When air filters become clogged, the engine can experience rough idling, reduced acceleration, and decreased overall power. This underperformance can also lead to increased fuel consumption, as the engine may work harder to draw in air, thus negating any potential fuel efficiency gains. Overall, a clean air filter is essential for maintaining optimal engine performance and efficiency, which is why recognizing the impact of a clogged filter is crucial for vehicle maintenance.
