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!
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.
