If you're wondering how much it costs to change a filter, the answer depends on the type of filter and the vehicle you drive. Generally, it's best to replace your engine air filter every 10,000 miles, even if it's still doing its job. If you're in an area with a lot of sand or dust, such as a beach or desert, you'll need to replace the filter more often than recommended. When you take your car for regular maintenance, the mechanic will usually inspect the engine air filter for dirt.
If they find that it needs to be replaced, they'll tell you. The cost of the filter itself will depend on the type of vehicle you have and whether you buy an OEM or universal-fit filter. OEM filters are designed specifically for your vehicle assembly, while universal-fit filters are based on shape and dimensions. Along with the cost of the filter, you'll also have to pay for labor.
If you think your air filter is causing problems with fuel efficiency or power, you should change the filters immediately. You can also try brushing dirt off the surface and turning the filter 180 degrees to expose the cleaned area to the main airflow. If there is a lot of sand or dust in the air, such as a beach or desert, you'll need to replace the filter more often than recommended. If you have started to notice a reduction in fuel consumption or if your engine is idling roughly and the engine light has come on, it's time to replace the air filter.
While these symptoms could also indicate other problems with your car, checking your air filter is quick and easy. If you can smell smoke or if your car makes a loud exhaust sound, it's time to replace the air filter. If you are unsure of any of the steps or are having trouble locating your air cleaner box, always refer to your owner's manual for more information.
