5 Signs Your Car's Air Filter is Clogged

5 Signs Your Car's Air Filter is Clogged | Crompton's Auto Care

Is your car struggling to breathe? Your air filter might be to blame. We'll share five common signs that indicate your car's air filter is clogged and needs attention. Don't overlook these warning signals – addressing them promptly can prevent costly damage and keep your engine running smoothly.

1. Decreased Acceleration and Power

If you've noticed a decrease in your car's acceleration and overall power, a clogged air filter could be the culprit. A restricted airflow caused by a dirty filter can starve your engine of the oxygen it needs to perform optimally, resulting in sluggish acceleration and reduced power output.

2. Poor Fuel Economy

Are you making more frequent trips to the gas station than usual? A clogged air filter can lead to poor fuel economy by forcing your engine to work harder than necessary. With inadequate airflow, your engine compensates by burning more fuel to maintain performance, ultimately decreasing your gas mileage.

3. Dirty or Dark Exhaust Smoke

Examine your car's exhaust pipe – if you notice dark or dirty smoke emitting from it, a clogged air filter could be to blame. A restricted airflow caused by a dirty filter can disrupt the air-fuel mixture in the engine, leading to incomplete combustion and the production of dark exhaust smoke.

4. Unusual Engine Sounds

Listen carefully to your engine while it's running – if you hear unusual sounds like wheezing, rattling, or whistling, it could indicate a clogged air filter. These sounds occur as your engine struggles to draw in enough air through the dirty filter, resulting in turbulence and vibrations within the intake system.

5. Check Engine Light Illuminates

A clogged air filter can trigger your car's onboard diagnostics system to illuminate the check engine light. This warning light serves as an early indication of potential issues with your vehicle, including a clogged air filter. Ignoring the check engine light can lead to more severe engine problems down the road.
