OEM Subaru Air Filters

Filter

Odds are, your Subaru vehicle came with two factory-installed air filters in place. One is for the engine, while the other is for your cabin's HVAC system. They both have the same purpose: to keep contaminants from entering your vehicle's systems.

What Car Air Filters Do

The engine air filter is usually located near the air intake. It prevents airborne pollutants and debris from gathering in your engine and causing problems.

The cabin air filter is most often found behind the glove compartment, though it's sometimes placed underneath the front, cowling on some vehicles. This air filter captures allergens and irritants before they can sneak into the cabin through the air vents.

Unfortunately, even the highest quality air filter will degrade with age if it doesn't get too clogged up first. When that happens, you'll notice either your engine performance or interior air quality suffer as a result.

How to Spot Failing Air Filters

Signs of trouble include:

  • Misfiring engine
  • Impaired engine output
  • Poor acceleration
  • Reduced fuel economy
  • Odd noises coming from the engine
  • Musty smelling cabin
  • Inability to maintain a consistent cabin temperature
  • Whistling noise coming out of the air vents
  • Dark exhaust smoke
