2006 SUBARU LEGACY air filter

Climate control 4-13
Air filtration system (if
equipped)
If your vehicle’s air conditioning system is
equipped with an air filtration system, re-
place the filter element according to the
replacement schedule shown in the fol-
lowing. This schedule should be followed
to maintain the filter’s dust collection abili-
ty. Under extremely dusty conditions, the
filter should be replaced more frequently.
Have your filter checked or replaced by
your SUBARU dealer. For replacement,
we recommend the use of a genuine
SUBARU air filter kit.
Replacement schedule:
Every 12 months or 9,300 miles (15,000
km) whichever comes first
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
Contact your SUBARU dealer if the
following occurs, even if it is not yet time to change the filter:
– Reduction of the air flow through the vents.
– Windshield gets easily fogged or misted.

Air cleaner element
The air cleaner element functions as a fil-
ter screen. When the element is perforat-
ed or removed, engine wear will be exces-
sive and engine life shortened.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the ele- ment. „Replacing the air cleaner ele- ment
Replace the air cleaner element according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. Under
extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. T

1) Connector
2) Duct
3) Clamp
1. Unplug the connector that is attached
to the top of the air cleaner case.
2. Remove the hose that is located at the
bottom of the side surface of the air clean-
er case.
3. Undo the screw and pull the air duct
out of the air cleaner case.
4. Unsnap the two clamps holding the air
cleaner case cover. 5. Open the air cleaner case cover and
remove the air cleaner element.
6. Clean the inside of the air cleaner cov-
er and case with a damp cloth and install
a new air cleaner element.
Do not operate the engine with the
air cleaner element
removed. The air
cleaner element not only filters in-
take air but also stops flames if the
engine backfires. If the air cleaner
element is not installed when the en-
gine backfires, you could be burned.
