Car air filters: got questions about auto air filters? We have answers!
What does an auto air filter do?
Your auto air filter removes pollutants from the air as it is drawn into your engine's air intake. This air is used in the combustion of fuel at a rate of 10,000 gallons of air to one gallon of gas.
At the same time, pollutants in the air consumed by your car can result in decreased engine performance, poor fuel economy and increased engine wear. These pollutants can make their way into your vehicle's fuel and engine oil if your air filter is not changed regularly.
Your engine gets its power from a mixture of fuel and air. The air filter traps dirt and contaminants, keeping the incoming air clean and improving engine performance.
How do auto air filters work?
Think of your vehicle as "breathing" air. If the auto air filter isn’t changed, your vehicle can’t operate properly. Would you want to run if you couldn’t breathe?
What will happen if I don’t change the auto air filter?
Besides damaging your engine, you’ll experience lower gas mileage and reduced engine performance, and you’ll contribute to air pollution.
How often does an auto air filter need to be changed?
Check your air filter every time you change your oil. Standard car air filters are good for about 7,500 miles, depending on driving conditions. Premium car air filters are made to last longer, even for the life of the vehicle.
