All cylindrical variations of the AMSOIL air filters are designed to be used
for up to 25,000 miles of service or one year under normal driving conditions.
Under continuous dusty driving conditions the air filter should be serviced more
frequently.
Initial Cylindrical Filter Installation:
1. Remove
the dirty air filter from the air filter housing/box. Carefully clean inside the
housing with a shop towel being careful not to wipe or knock contaminants into
the engine's air inlet.
2. Remove the new AMSOIL air filter from its plastic
packaging.
3. All cylindrical AMSOIL filters, regardless of their various
shapes, are installed the same way. Carefully place the filter in the housing
box and work it in until it comes in complete contact with the housing's sealing
ridge/edge.
4. Air Deflector Installation: (see photo at left): The
best place to install the aluminum air deflector is at the air inlet to the filter
housing. If your vehicle has a permanently installed air deflector at the air
inlet, install the aluminum air deflector at the filter housing's PCV (positive
crankcase ventilation) inlet. In either case:
a. Place the "narrow
edge" of the aluminum deflector under the bottom of the filter's foam
surface. IMPORTANT! Install under the edge of the foam only, not into or
under the metal cage.
b. Properly installed, the "air deflector"
maximizes airflow around the entire filter and stops the incoming airflow from
directly impacting the air filter in just one spot.
NOTE: In vehicles
with permanently installed air deflectors at the air intake and the PCV inlet
(if applicable), discard the aluminum air deflector.
5. After carefully
reinstalling the air filter housing cover, affix the AMSOIL air filter label to
the housing cover, filling in the installation date and vehicle mileage.
The
AMSOIL Air Filter may be cleaned and re-oiled at regular intervals. When properly
serviced, it never quits filtering!
Service Instructions:
While
some mechanics and users may choose to install a new air filter after receiving
the benefit of AMSOIL:s extended service protection, you do have the option of
further extending the air filter service life if the filter is in good condition.
Should you choose this option you must properly clean and re-oil the foam filter
media:
1 . Remove the air filter from the filter housing. Carefully clean
inside the housing with a shop towel being careful not to wipe or knock contaminants
into the engine's air inlet.
2. CAREFULLY remove the foam from the
wire frame (do not stretch out the foam). Wash the foam filter media in detergent
and water. Alternately, you can wash the filter in cleaning solution. However,
gasoline and other fuels are not recommended for safety reasons and due to their
adverse affect on the foam filter media. RINSE THE FILTER MEDIA THOROUGHLY
WITH CLEAN WATER AFTER WASHING.
3. (Very important!) ALLOW
FOAM MEDIA TO DRY THOROUGHLY.
4. Re-oil foam filter media with AMSOIL
Foam Filter Oil (other oil substitutes are not recommended). Use enough
oil to completely saturate the entire foam filter media.
5. Work the AMSOIL
Foam Filter Oil into the filter foam media with repeated squeezing and "make
sure" it is completely and thoroughly massaged into the entire
thickness/depth of the foam media. Blot excess oil from the filter media.
6.
Carefully reinstall the oiled foam filter media onto the wire cage, making sure
you have a proper fit with "complete wire cage coverage."
7. Reinstall
oiled air filter into the housing according to Filter Installation instructions
3, 4 and 5 above and record the service date and vehicle mileage on the label.
