CHANGING THE ENGINE AIR FILTER
WARNING: To reduce the risk of vehicle damage and personal burn injuries, do not start your engine with the air cleaner removed, and do not remove it while the engine is running.
Note: Failure to use the correct air filter element may result in severe engine damage. The customer warranty may be void for any damage to the engine if the correct air filter element is not used.
When changing the air filter element, use only the air filter element listed. See Motorcraft Parts (page 224). The air filter element should be replaced at the appropriate intervals. See Normal Scheduled Maintenance (page 250).
