automotive maintenance tutorial was specifically written to assist
owners of the sixth generation (2009, 2010, 2011, 2012, 2013, 2014,
2015 and possibly also the 2016 model year) Ford Fiesta sedan or
hatchback in cleaning or changing the engine air filter for the
Duratec 1.6 liter inline four cylinder Ti-VCT motor. Owners of other Ford vehicles equipped with the Sigma series of engines including the Zetec or Duratec versions including the Focus, Fusion, Puma, EcoSport C-Max and Mondeo may also find these DIY instructions to be helpful. A few compatible replacement engine air filters with their part numbers are as follows: Motorcraft FA-1904, Fram CA10997, K&N 33-2955, Mahle LX 3157, Ecogard XA6140, Wix 49604, Hastings AF1486, Pentius PAB10997, Luber-finer AF4904 and GKI AF10997. The only tool needed to access and replace the air filter is a Torx T-25 star bit screwdriver. |

 Lift Off Top Half Air Box |
| The engine air box
is located at the right front corner of the engine bay just in in front of
the 12V automotive battery. The top half of the air box is held in place by four screws. Loosen the four screws by turning them counterclockwise with a Torx T25 star bit screwdriver. The screws will remain attached to the air box cover. Carefully lift the top half of the air box off the lower half. |

 Clean With Vacuum |
 Clean Out Bottom Half |
| If the old filter
is relatively clean, just tap out the large debris and remove any fine dust
with a vacuum. If the old filter is dark grey or black and clogged with dirt, dust, pollen, hair, leaves, insects, twigs and other debris, it should be replaced with a new element. I always buy the Ford OEM Motorcraft FA-1904 engine air filter since it has excellent reviews on Amazon. If you'd prefer to have a re-usable filter that will last the life time of the car, go with the K&N 33-2955 filter which will need to be washed and re-oiled every 50,000 miles. Clean out any sand in the bottom half of the air box with a vacuum. |

 Lower In New Air Filter |
 Replace Top Half Air Box |
 Re-Insert Torx T25 Screws |
|
Lower the new air filter in to the lower half of the air box with the pleats facing down. Due to the filter's irregular shape, it can only be inserted in one way. Lower the top half of the air box down in to place over the lower half. |

 Tighten Screws Clockwise |
 Tighten All 4 T25 Screws |
 Engine Air Filter Replaced |
| Tighten the four
screws (one located at each corner) by turning them clockwise with the
Torx T25 screwdriver until they are snug. Try to avoid over tightening the screws to prevent from cracking the plastic air filter housing. For more,
