Service & Maintenance

In normal, on-road applications, service your K&N Filter every 50,000 miles. A certain amount of dirt build-up will actually work for you. It does not degrade performance and helps filter the air.

Service the filter more frequently if it is subjected to frequent or heavy dust. Regular operation in a fine dust environment, such as what would be present for agricultural, construction or off-road use, will cause oil loss from the element. Frequent re-oiling of the element's clean side may be required.

NOTICE: Please read the following instructions.

Cleaning:  Use only K&N Filter Cleaner. It is available in either spray-on or liquid form. Do not clean K&N Filters with gasoline, solvents, parts cleaners, strong detergents or caustic cleaning solutions. Do not steam clean or use high pressure car washes to clean a K&N Filter. Any of those processes will damage filter media and/or the rubber base, top or end caps.

Drying: After rinsing, shake off the excess water and let the element dry at room or outside air temperature. Many people hang filters on a clothes line to dry. Do not use compressed air because it will damage the filter media. Do not use heat from any source to dry a K&N Filter. Heat will shrink the filter media and may damage the rubber base, top or end caps.

Oiling: Never put a K&N Filter in service without oiling it. The filter will not function properly without being oiled. Use only K&N Filter Oil or the filter will not function properly. K&N Filter Oil is a unique blend of mineral and organic oil base stocks and special polymers that form a very efficient “tack barrier.” Red dye is added to show areas of oil application. Eventually, the dye fades but the oil remains to filter the air. Do not use automatic transmission fluid, any kind of motor oil or diesel fuel to oil a K&N Filter. Do not use “WD-40”, “LPS” or any other type of light-weight spray lubricants to oil a K&N Filter. Any of those products will damage the filter or degrade its filtering ability. A K&N Filter used on an engine that is regularly operated in a fine dust environment will require frequent re-oiling of the filter’s clean side in between cleanings.

Service K&N Filters only with K&N Air Filter Cleaner and K&N Air Filter Oil.

"Easy 4 Step Cleaning Process"

PRE-CLEANING:

Tap the K&N Filter gently on a hard surface to dislodge loose dirt. Tap the base of a round filter. Tap a panel filter dirt side down. Do not tap any filter on its edges. Remember to tap gently. Next, gently brush the dirt side of filter with a soft bristle brush.

SPRAY CLEANING:

Spray K&N Air Filter Cleaner liberally onto the entire element. Let the Cleaner soak into the filter media for 10 minutes.

K&N Elements can be rolled or soaked in a shallow pan of K&N air filter cleaner. Remove immediately and let soak for approx. 10 minutes.

Do not agitate the filter in the Cleaner.

RINSE:

Rinse the element with low water pressure, use of tap water is preferred. Always flush from the clean side to dirty side. This removes the dirt and does not drive it further into the filter media.

SPRAY OILING:

Spray K&N Air Filter Oil  Spray oil down into each pleat with one pass per pleat. The filter media will become a reddish color.  Let the filter sit for 10 minutes then re-spray any areas that are still white.

REINSTALL:

Re-install your K&N Air Filter with care. In some applications, especially off-road use, it may be necessary to use K&N Sealing Grease on rubber base, top or end caps of the filter. Make sure the element seats properly in the filter housing. Install the cover and tighten all the nuts, bolts, screws or clips to the manufacturer’s specifications.
