How do you replace the air filter on a Ford Fiesta 2003?

Hello there;

-You should open 2 screw in front of air filter box

-Disconnect two air pipe connected to the box and a tiny pipe as well(these are very easy)

-Disconnecting the box from engine is the more difficult part of work you think that you must break some things so you have to pull the back part of the air filter box firmly ,I pull the right first and disconnect that then the left pin is easyer(there are two pin which keep this box on the engine)

-Underneath of the box are 10 screw that you need to open them to reach air filter(you need a long wrench,about 5 cm length which i bought from Pound Land or a simple screw driver)

-The rest is very simple
