Engine Air Filter Replacement

Model: Ford Focus MK 3 - Years 2011-2018
Part: Air filter

The air filter housing is located inside the engine bay, just behind the driver’s side headlamp; unscrew the fixing screws of the filter box cover, remove it, and extract the filter from its seat. Clean the filter box of any debris, taking care not to let any enter the intake duct (avoid shaking the filter directly above the box as shown in the video).
Then insert the new filter (or blow out the old one with compressed air) ensuring the central fitting adheres correctly to its support. Finally, reposition the cap and tighten the respective fixing screws.
