What Is An Engine Air Filter And Why Is It Important?

Looking for a quick and easy way to improve your Toyota's performance? Change the engine's air filter! What's an engine air filter, and how does it help protect the engine? Read on to find out.

What's an Engine Air Filter and Why Does Your Car Need One?

Change air filter

Located inside a cold air collector box near the front of the engine compartment, the engine air filter is a rectangular pleated filter. It traps particles like dirt, bugs, and other debris in the air before it flows into the engine. In other words, the engine air filter only allows clean air into the engine.

If the engine is exposed to unfiltered air, it will wear out faster. Dust is harmless in small volumes, but in large quantities it is abrasive. Engines suck in a tremendous amount of air. If dust comes in with the air, the dust will damage internal engine components. It is not cost efficient to replace the worn components, so most people end up with a new or used engine.

The Benefits of Changing the Engine Air Filter

It's common to change an engine air filter every 15,000 miles. Engine air filter changes need to be more frequent if you live in a rural area or a dusty environment. Regular engine air filter changes help maintain the level of airflow your engine is supposed to get, which is hugely beneficial in several different ways:

  • Better fuel economy
  • Improved acceleration
  • Reduced emissions due to correct air/fuel mixture
  • Prolonged engine life
