The air filter plays a crucial role in regulating the amount of air entering the engine. If the air filter is clogged o r dirty, it restricts airflow, which causes the engine to burn more fuel to compensate for the lack of air. This results in poor fuel economy.

How it Affects the Engine: With a clogged air filter, the engine cannot get enough oxygen, which leads to a richer air-fuel mixture. This means more fuel is injected into the engine than necessary, reducing fuel efficiency.
Symptoms of a Dirty Air Filter: Poor acceleration, rough idling, decreased engine performance, o r increased fuel consumption are common signs of a clogged air filter.
Solution: Replace the air filter at regular intervals as specified in your cars manual to ensure smooth airflow to the engine and better fuel economy. A clean air filter also helps prevent other engine-related issues.
