2. Remove the air filter cover: Depending on your vehicle, the air filter cover could be secured with screws, clips or latches, so you need to remove them.
3. Check the current air filter: Take out the current air filter and check its condition. If it's dirty, clogged or damaged, it needs to be replaced.
4. Replace the air filter: Insert the new air filter to the same position as the old one. Follow the instructions on the filter to ensure proper placement.
5. Replace the air filter cover: Place the cover back to its position and secure it in place with clips, latches, or screws.
6. Test run: Start your car and let it run for a few minutes, then turn off the engine and check the air filter to ensure it's properly installed.It's recommended to change the air filter at least once a year or more frequently if you use your car in dusty or polluted environments.
