Engine & Cabin Air Filters

Checking or replacing the air filters in your car.

Every engine has an air filter and it can get really dirty under the hood.

Your air filter is what protects your engine from ingesting all the dust and dirt in the air. If it’s doing its job well, it can clog up, much like a vacuum cleaner. A dirty air filter will limit airflow making your engine work harder and potentially decreasing your fuel economy.

What you may not know is that your car actually has a second air filter called a cabin air filter. This filter’s located directly in the HVAC system and actually works very similar to the furnace filter in your house. It blocks all the air coming in to the cabin of the vehicle which would be the air that you’re breathing.

When these filters become clogged, it’ll actually put more stress on the air conditioning and the heating system blowing through the vents.

You should always check your vehicle’s owner’s manual for mileage recommendations but most manufacturers recommend at least once every 12 months or 12,000 miles whichever would come first.

A tip to help you remember when to change those filters is write it down on a piece of tape and stick it to the airbox. This way you’ll know when the last time it was changed.

That’s your tip of the day from Under The Hood.
