Remove the screws or clips securing the housing.
Take out the old filter and clean the housing with a damp cloth.
Install the new air filter, ensuring it is seated properly.
Resecure the housing.

3. Inspect and Replace Fuel Filter (if necessary)

Locate the fuel filter in the fuel line (refer to the vehicle manual for specific location).
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Use a wrench to disconnect the fuel lines from the filter, being cautious of residual fuel.
Remove the old fuel filter and replace it with a new one, ensuring correct orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the intake duct and ensure it is secured properly.

5. Check and Replace Spark Plugs (if necessary)

Remove the ignition coil packs by unscrewing them from the engine.
Take out the old spark plugs using a spark plug socket and ratchet.
