To replace the air filter that feeds the injection system of the Ford Focus, we open the hood of the engine compartment, and we find the filter box on the driver's side between the battery and the front. We unscrew the four 7mm screws with a socket wrench equipped with an extension, using a magnet to prevent the screw from getting lost once unscrewed.

We remove the cover and slide out the old cylindrical filter element, clean the compartment with a vacuum cleaner. Insert a new filter, with the same characteristics as the previous one, close the cover and lock it by screwing the four screws.
