Introduction
Your car’s air filter helps keep dirt, dust, and debris out of the engine. When it gets clogged, your engine has to work harder — reducing efficiency and increasing emissions.
How Often Should You Replace a Car Air Filter?
Most manufacturers recommend replacing the air filter every 12,000 to 15,000 miles, or once a year. However, if you drive in dusty or polluted areas, you may need to change it more frequently.
Signs You Need a New Air Filter
- Reduced acceleration or sluggish performance
- Decreased fuel efficiency
- Dirty or discolored filter
- Check engine light turns on
- Strange engine sounds
Cabin vs. Engine Air Filter
Don't confuse the cabin air filter (for A/C) with the engine air filter. This guide focuses on the engine filter, which directly affects performance.
Tips to Extend Filter Life
- Avoid driving on dirt roads when possible
- Keep your hood sealed to prevent extra debris
- Inspect your filter at every oil change
