2003 FORD SUPER DUTY width

Note:Do not start your engine with the air cleaner removed and do not
remove it while the engine is running.
Changing the air filter element (gasoline engines only)
1. Loosen the clamp that secures
the air filter element in place.
2. Carefullyseparate the two halves
of the air filter housing.
3. Remove the air filter element
from the open end of the air filter
housing.
4. Install a new air filter element, ensuring the arrow on the top half of
the air filter housing lines up with the notch on the bottom half of air
filter housing. Be careful not to crimp the filter element edges between
the air filter housing. This could cause filter damage and allow
unmetered air to enter the engine if not properlyseated.
5. Replace the two halves of the air filter housing and secure the clamp.
