Air Filter Element Maintenance
  1. Inspect the air filter element every 8,000 km (5,000 mi), or more often under dusty conditions.
  2. NOTE
    • The use of cleaning, drying or oiling methods or products other than those shown damages the filter and void the manufacturer's warranty
    • K&N® Air filter Cleaner is available from a Harley-Davidson dealer. 1 qt/0.95 L sprayer bottle, (Part No. 99883-88T) or a 12 fl oz/0.35 L sprayer bottle as part of the Filter Care Service Kit (Part No. 99850-92T).
    • K&N Air Filter Oil is also available from a Harley-Davidson dealer. (12.25 oz/347 gram aerosol can, Part No. 99882-88T) or a 6.5 oz/184 gram aerosol can as part of the Filter Care Service Kit.
    • DO NOT OVER-OIL THE AIR FILTER. Over-oiling may interfere with the proper performance of the engine and/or certain engine components. If oil is still draining or dripping from the filter media 20 minutes after oiling, clean and oil the filter element again.
  3. To clean the element:
    1. Remove the air cleaner cover center screw.
    2. Tap the element to dislodge any loose dirt. Gently brush with a soft bristle brush.
    3. Spray air filter cleaner liberally onto the cotton filter media. Let soak for ten minutes OR roll and soak the cotton filter media in a shallow pan of air filter cleaner. Remove immediately, and let soak for ten minutes.
    4. Rinse off the filter media (flowing from the clean side to the dirty side), with low-pressure tap water.
    5. After rinsing, shake off all excess water, and let the filter media air dry. DO NOT use compressed air or a heat gun to speed drying.
    6. After the filter media is completely dry. EITHER spray air filter oil along each pleat, once only, holding the spray nozzle approximately 76 mm (3 in) away from the media, OR carefully use a squeeze bottle to deposit oil along each pleat, once only. Let the oil absorb into the filter media for 20 minutes before proceeding. After 20 minutes, inspect the filter media. Carefully apply oil to any remaining visible white spots on the filter media. Allow to absorb.
