Introduction
Air filters are typically replaced every 15,000 miles, but a cleaning between replacements can enhance your car's performance. If you've noticed a decrease in mileage per gallon or acceleration, try vacuuming and gently cleansing the air filter. It could be just what your car needs.
Air filters are made of cotton, paper or foam, or a mix of those materials. Check your owner's manual or with the air filter manufacturer to be sure it's safe to use soap and water, and if you have an oil-coated filter. Oil-coated filters aren't as common, but if you have one, you'll need a specific cleaning solution. Don't use soap and water on an oil-coated air filter.
