Dangers of overused engine air filter that has become flaky

I have seen cars with very old and overused air filters. These air filters are so bad that they are not only blocked but have become flaky. The air filter begins to disintegrate on its own and the particles find their way into the combustion chamber.

The photo that is attached is a photo of an engine air filter that has been left unchanged, blocked, has become flaky and has started disintegrating.

Apart from parts of the air filter posing a risk to the engine, it can also allow other foreign materials to gain access to the engine.

A good preventive maintenance practice is to change the engine's air filter regularly.

Other benefits of changing the engine's are filter periodically are;

  1. Reduced contamination of the engine oil as less dust particles will find their way into the engine
  2. Cleaner Mass Airflow meter or Manifold Absolute Pressure sensor
  3. A good air filter helps to maintain the engine's power
  4. A good air filter helps to maintain good fuel economy.
