CHANGING THE ENGINE AIR
FILTER - 3.5L ECOBOOST™
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.
Note: 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.
When changing the air filter element, use
only the air filter element listed. See
Capacities and Specifications (page
295).
Change the air filter element at the proper
interval. See Scheduled Maintenance
(page 436).
