1. Preparation

Tools Required:
- Flat-head screwdriver or Torx driver (depending on the fasteners)
- Clean cloth or vacuum
Park the vehicle on a flat surface and turn off the engine. Allow it to cool.
Open the hood and secure it with the prop rod.

2. Remove the Engine Cover (if applicable)

Locate the fasteners on the engine cover.
Use the appropriate tool to remove the screws or bolts holding the cover in place.
Carefully lift the engine cover off and set it aside.

3. Access the Air Filter Housing

Locate the air filter housing, which is typically a black plastic box near the engine.
If there are any clamps or screws securing the housing, remove them using the flat-head screwdriver or Torx driver.

4. Remove the Old Air Filter

Carefully lift the air filter out of its housing. Avoid letting debris fall into the intake manifold.
Inspect the air filter for any signs of damage or excessive dirt.

5. Clean the Air Filter Housing

Use a clean cloth or vacuum to remove any dirt or debris from inside the air filter housing.
Ensure the housing is clean and free of obstructions.

6. Install the New Air Filter

Place the new air filter into the housing, ensuring it fits snugly and is oriented correctly (the rubber seal should be seated properly).
Re-secure the air filter housing by reattaching any clamps or screws removed earlier.
