Cleaning Filter Element
All except round high flow
NOTE
  • Do not strike filter element on a hard surface to dislodge dirt.
  • Do not use air cleaner filter oil on the Harley-Davidson paper/wire mesh or synthetic air filter element.
    WARNING
    Do not use gasoline or solvents to clean filter element. Flammable cleaning agents can cause an intake system fire, which could result in death or serious injury. (00101a)
    WARNING
    Compressed air can pierce the skin and flying debris from compressed air could cause serious eye injury. Wear safety glasses when working with compressed air. Never use your hand to check for air leaks or to determine air flow rates. (00061a)
  1. Clean filter element.
    1. Wash the breather tubes(if equipped) and filter element in lukewarm water with a mild detergent.
    2. Synthetic element: Rinse filter element with clean water. The filter element is sufficiently clean when water running from the filter element appears clear.
    3. Allow filter element to air dry or use low-pressure compressed air from the inside.
    4. Paper/wire mesh element: Hold the filter element up to a strong light source. The element is sufficiently clean when light is uniformly visible through the media.
    5. Replace the filter element if damaged or if filter media cannot be adequately cleaned.
Round high flow only
NOTE
  • The use of cleaning, drying or oiling methods or products other than those specified here, damages the filter and can void the manufacturer's warranty.
  • K&N Air Filter Cleaner and Air Filter Oil is available from a Harley-Davidson dealer.
  • DO NOT OVER-OIL THE AIR FILTER. Over-oiling can 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.
1. Clean filter element.
a. Tap the element to dislodge any loose dirt. Gently brush with a soft bristle brush.
b. Spray air filter cleaner liberally onto the cotton filter media and let soak for ten minutes, OR roll or soak the cotton filter media in a shallow pan of air filter cleaner. Remove immediately, and let soak for ten minutes.
c. Rinse off the filter media (flowing from the clean side to the dirty side), with low-pressure tap water.
d. 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.
e. After the filter media is completely dry, EITHER carefully use a squeeze bottle to deposit air filter oil along each pleat, once only, OR spray oil along each pleat, once only, holding the spray nozzle away from the media approximately 76 mm (3 in).
f. Let the oil absorb into the filter media for 20 minutes before proceeding.
g. After 20 minutes, inspect the filter media. Carefully apply oil to any remaining visible white spots on the filter media. Allow oil to absorb.
Rain Sock
If equipped with oval air cleaner:See Figure 4. In wet or rainy conditions, because the filter element is exposed, water can enter the engine. When parked, water can cause internal engine corrosion or damage. When running, water can cause the engine to misfire. In wet or rainy conditions, install the rain sock (6) over the air cleaner assembly to minimize water intrusion.
