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

Every Nissan has an engine air filter. You will find one in your engine's air intake system. It's a part that requires regular maintenance.

What Does An Engine Air Filter Look Like?

If you look inside the intake air collector box, you'll find the engine air filter. It has a square or rectangular shape. A soft pliable gasket runs around the perimeter of a pleated filter.

What Does An Engine Air Filter Do?

The engine air filter is different from the cabin air filter. The engine air filter cleans the air before it enters the engine. It traps the following impurities:

  • Dust
  • Dirt
  • Bugs
  • Sand
  • More

An automobile engine consumes a very large amount of air. A typical 2.0 liter engine uses about the same amount of air as a household vacuum cleaner when it is cruising at 2000 rpm. But a typical engine will run many more hours in a year than a typical vacuum.

What Happens When Unfiltered Air Enters The Engine?

Unfiltered air has a negative effect on the engine. The impurities in the air speed up wear and tear inside the engine. They may also contaminate the motor oil and cause friction between the internal engine components.

When engine components wear out, the most common solution is to replace the engine. It's not cost effective to take the engine apart and then replace only the worn components. Believe it or not, but it's cheaper and easier to replace the entire unit. But, this is still very expensive. 

Even though the engine air filter is small and disposable, it plays a big part in your engine's health. So it's important to replace the engine air filter often.

A good rule of thumb is to replace your engine air filter every 15,000 miles. If you live in a rural or dusty area, you should change your engine air filter more often.

If you don't change your engine air filter, it gets clogged up. This deprives the engine of air. If your Nissan's engine doesn't receive a steady flow of clean air, the following problems crop up:

  • Reduced engine performance
  • Reduced fuel economy
  • Potential deterioration of engine components

Regular replacement of the engine air filter brings huge benefits, including:

  • Better engine performance
  • Longer engine lifespan
  • Better fuel economy
  • Improved acceleration
