Step-by-Step Guide to Replace Your Car’s Air Filter
Step 1: Locate the Air Filter Housing
The air filter is typically housed in a rectangular or cylindrical box under the hood of your car. Look for a plastic or metal casing secured with clips or screws. Your vehicle manual can help you identify the exact location.
