What is an air filter?

Your car or truck engine gets oxygen from an air intake for the combustion process which releases energy from fuel. Engine air filters allow oxygen to reach the engine while filtering out airborne particulates like dust, insects, allergens, and pollutants. Maintaining a clean air filter can help with fuel economy.

How often should you change the air filter in your car?

NAPA recommends you change your air filter every 15,000 miles or once a year at a minimum. If you drive in especially dirty or dusty areas, consider changing it more often.

What are the signs that you might need to replace your air filter?

If your vehicle is experiencing symptoms like decreasing gas mileage, reduction in horsepower, black smoke or smog from exhaust pipe, or a strong fuel smell, it may be because you have a dirty air filter. Each time you change the oil in your vehicle, the car's air filter should also be inspected to check if it is showing any signs of contamination. Many small contaminants can make the engine's air filter dirty, impacting cabin air flow, limiting clean air quality, and potentially causing damage to your car's engine performance. If you see the "check engine light" sign on your dashboard, this may be a sign that you need a new air filter.
