CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
or personal burn injuries, do not start
your engine with the air cleaner
removed and do not remove it when the
engine is running.
When changing the air filter element, use only
the air filter element listed. See Capacities
and Specifications (page 290).
For EcoBoost equipped vehicles, when
servicing the air cleaner, it is important that
no foreign material enter the air induction
system. The engine and turbocharger are
susceptible to damage from even small
particles.
Change the air filter element at the proper
interval. See Scheduled Maintenance
(page 392).
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.

Release the clamps that secure the air
filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the air

4. Wipe any dirt or debris from the air filter
housing and cover to make sure no dirt
gets in the engine and to make sure you

unfiltered air to enter the engine if not
