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. Do not remove the air cleaner
while the engine is running.
When changing the air filter element, use
only the air filter element listed in the
Motorcraft Parts table. See Motorcraft
Parts (page 264).
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 405).
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.
