Knowing the signs of a dirty air filter helps you keep your car in good shape. It can save money and avoid bigger repairs.
Reduced Engine Power
A dirty air filter limits airflow to the engine. The engine may feel weak or slow. It can take longer to speed up or climb hills.
Poor Fuel Efficiency
When the air filter is clogged, the engine burns more fuel. You may notice you fill the tank more often. This can increase your fuel costs.
Unusual Engine Sounds
A dirty air filter can cause the engine to make strange noises. You might hear coughing, popping, or sputtering sounds. These noises mean the engine is not getting enough air.
Check Engine Light Comes On
