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.
