Air Filter Element: Description and Operation
AIR INDUCTION SYSTEM
Air enters a dry-type engine air cleaner and travels through a pleated, chemically treated, water resistant paper air cleaner element to remove
contaminants before entering the engine induction system. The 7.3L Direct Injection (DI) turbo diesel engine also uses a pleated-paper upright
type element. Use of other than specific Ford replacement filters may result in significantly shortened filter life and consequent dirt injection.
AIR CLEANER ELEMENT
Dry-type engine air cleaners are standard on all vehicles.
Air enters the engine air cleaner and travels through a chemically treated and pleated paper air cleaner element before entering the engine
induction system. The air cleaner element should be inspected, cleaned, or replaced periodically according to the maintenance schedule. The air
cleaner system has an Intake Air Temperature (IAT) sensor mounted in the engine air cleaner to monitor inlet air temperature.
Air Restriction Gauge
On diesel engines, replace air cleaner element according to air restriction gauge.See: Testing and Inspection
