GM Air Filters

These days, most cars, SUVs, pickups, and vans have two types of air filters. One is for the engine, while the other is for the HVAC system in your cabin. They do the same thing as your oil filter and fuel filter do, which is to protect essential systems from airborne contaminants and debris.

Where Are Your Air Filters?

The engine air filter is located near your air intake, making it easier for it to capture the pollutants before they make their way to the engine. Without the engine air filter, your engine wouldn't be able to perform its best.

The cabin air filter is typically placed behind the glove compartment, though it can also be found under the front cowling on the passenger side of your vehicle. It's responsible for keeping allergens and irritants out of the air ducts, where they can pass into the passenger space. Without it, the air you breathe would be much less clean.

When Should You Replace Your Air Filters?

Even the highest-quality air filter will either degrade with age or get too clogged up to work properly. When that happens, you'll want to replace it to ensure clean air flows as it should. Signs of failure include:

• Engine misfires
• Engine makes odd noises
• Weaker engine horsepower
• Cabin smells musty
• Inconsistent cabin temperature
• Air vents make whistling sounds

If you're not experiencing any of these symptoms, check your owner's manual. It will tell you the recommended maintenance schedule you should follow. You should also make a regular practice of checking their condition.
