Replacing your car’s air filter is a crucial part of maintaining your vehicle. A clean air filter ensures optimal airflow to the engine, enhancing performance and fuel economy. Here’s how you can replace it yourself:

What Tools Do You Need?

Before you begin, gather the following tools:

• Screwdriver: Typically, a flathead or Phillips will suffice.

4. Inspect the Housing:

   • Before inserting the new filter, check the housing for dirt or debris. Wipe it clean with a damp cloth if necessary.

5. Insert the New Air Filter:

   • Place the new air filter into the housing, ensuring it fits snugly and is oriented correctly.

6. Secure the Housing Cover:

   • Replace the cover and secure it with screws or clips.

7. Check Your Work:

   • Ensure the cover is tightly secured and there are no loose parts.
