Is the engine air filter the same thing as the cabin air filter? What is the purpose of an engine air filter? How often does it need to be replaced?  We’ll answer all these questions and more in this blog.

What is an engine air filter?

The engine air filter is located in the car’s engine compartment and keeps dirt, dust, and debris out of the engine. 

What is the purpose of an engine air filter?

Just like face masks filter out particles in the air to make it safe for our lungs, an engine air filter allows clean air to enter the engine.

Is replacing your engine air filter important?

During the combustion process, the air that is filtered through the engine air filter is combined with fuel and ignites to power the engine. If your engine is unprotected from dirt and debris, it will wear out prematurely.  Dust in small doses is harmless, but over time it can damage the internal engine parts and you’ll end up replacing your engine before you know it.

Can I clean my engine air filter rather than replace it?

Cleaning your car’s engine air filter in between replacement is okay as long as there are no holes, rips, or tears in the filter.  Keep in mind cleaning the air filter is not a substitute for replacing it.

How often should an engine air filter be replaced?

It is recommended to replace the engine air filter every 15,000 to 30,000 miles depending on the driving conditions.  If you live in a dusty environment, you will need to replace it sooner.  A dirty or clogged engine air filter will block the airflow and make your engine work harder and decrease your fuel economy. 

What is the difference between an engine air filter and a cabin air filter?

A car’s engine air filter cleans the air that enters the engine while the cabin air filter cleans the air that enters your car through the HVAC vents.

How do I know if the engine air filter needs to be replaced?

If you have difficulty accelerating or notice the RPM is higher than normal, it’s probably time for a new engine air filter. A check engine light could also mean a dirty air filter. It’s a good idea to check the engine air filter (or have Hilltop Tire do it for you) at least once a year.

Where can I get an engine air filter replaced near me?

There are many different sizes and shapes of filters specific for each vehicle, so one size doesn’t fit all.  When it’s time to replace your engine air filter, stop by any Hilltop Tire Service location in Des Moines and our certified technicians can get a new one installed and have your engine running efficiently again in no time!

Can I replace the engine air filter myself?

Of course! If you’d rather replace the engine air filter yourself, it is a fairly simple task as long as you are familiar with working under the hood.

A clean air filter equals a happy engine!
