Most vehicles have two air filters: an engine air filter and a cabin air filter. These filters help keep dirt and debris out of the engine and cabin, ensuring a clean air supply for combustion.
Engine Air Filters
A dirty engine air filter can cause the engine to work harder, which may lead to power loss, dirty smoke, and other issues.
Cabin Air Filters
A clean cabin air filter protects against dust, mold, exhaust, and allergens. However, a dirty filter can reduce the efficiency of the heating and cooling system.
It’s recommended to change your air filters every 12,000–15,000 miles or once a year. Replacing your filters is affordable and can prevent costly damage down the road.
Some signs that your air filters need replacement include:
- Black smoke or flames from the exhaust pipe
- Check engine light is on
- Dirty air filters
- Jerking movements when you accelerate
- Misfiring and starting issues
- Reduced fuel efficiency
- Strange engine sounds
