How to know if Air-Filters need a replacement?

   Jun 12,2023

The engine's air filter plays a vital role in ensuring the intake of clean air, which is essential for the efficient and proper functioning of the engine. Typically, air filters are replaced during regular servicing. However, in situations where a vehicle is frequently exposed to dusty environments like construction sites or heavy traffic areas, the air filter may become clogged at a faster rate. In such cases, it becomes necessary to replace the air filter sooner than the regular maintenance schedule.


Signs that indicates air-filter replacement

Although air filters are essential for keeping dirt and dust out of your engine, they do require periodic replacement. Over time, they become clogged with the debris they have filtered out, affecting their efficiency. Look out for the signs.

  1. Strange sounds:

    Paying attention to the sounds your car makes can help you catch potential issues before they become costly. In the case of air filter problems, a deprived engine may produce abnormal noises that indicate that your air filter needs
  2. Black smoke from exhaust:

    An engine needs the right amount of fuel and air. This well- balanced composition guarantees effective fuel combustion in your car. However, black smoke coming from the exhaust becomes a visible sign of this imbalance when there is too much fuel in the combustion chamber but not enough oxygen for burning.
  3. Misfiring engine:

    A misfiring engine can result from unburned fuel, which forms soot These residuals accumulate on spark plugs, causing them to become dirty and inefficient. If you experience jerking when pressing on the gas pedal or encounter difficulty starting your car, this is a clear indication of air-filter replacement.
  4. A gasoline smell:

    When an air filter is blocked, it impedes the smooth flow of fuel through your engine, causing a shortage of oxygen. As a consequence, unburned fuel remains and does not undergo complete combustion. Instead, it exits through the tailpipe, emitting a distinct odor of gasoline.
  5. Decreased acceleration:

    If you notice a decrease in your car's performance and feel like it's not as responsive as before, the culprit could be a clogged air filter. When you press on the accelerator and your vehicle fails to provide the expected response, it may indicate that the engine is not receiving the necessary airflow to accelerate
  6. Check engine light:

    A clogged air filter restricts the airflow, leading to the accumulation of carbon This illuminates the check engine light. As the check engine light can activate for various reasons, it is important to check the diagnostic code to determine the specific issue. Seeking assistance from an experienced mechanic who can read the diagnostic code will help identify and address the problem accurately.

Wrapping up

Never underestimate the impact of a fresh air filter, as it plays a crucial role in maintaining the vitality of your car. Most owners’ manuals advise replacing the air filter every 12,000 to 15,000 miles. It is essential to regularly replace this key component of the air intake system to ensure optimal performance.
