1. SERVICE INTERVAL
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.
Service K&N Filters only with K&N Air
Filter Cleaner and K&N Air Filter Oil.
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. A old tooth brush works well.
3. CLEANING PRECAUTIONS
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.
4. SPRAY CLEANING
Spray K&N Air Filter Cleaner liberally onto the entire
element. Let the Cleaner soak into the filter media for 10 minutes.
5. PAN CLEANING
Most larger K&N Filters are easier to clean in a pan. Best
to use for larger round filters is a bread pan of adequate width and depth
such that a section of the filter can be dipped in the Cleaner. Fill the
pan with K&N Air Filter Cleaner to a level where the filter
media is just barely submerged. Rotate the filter once so all parts of it
go through the Cleaner. Do not agitate the filter in the Cleaner as
dirt removed from the dirty side may be redeposited on the clean side.
Remove the filter from the pan and set it aside. let the Cleaner soak into
the filter media for 10 minutes.
Panel filters are easier to clean in a roasting or turkey pan, such as
the disposable aluminum units found in grocery or cooking supply stores.
Place the filter in the pan and pour in the Cleaner to a level where the
filter media is just barely submerged. Do not agitate the filter in
the Cleaner. Remove the filter from the pan and set it aside. Let the
Cleaner soak into the filter media for 10 minutes.
After the Cleaner soaks for 10 minutes, rinse the filter with low
pressure water. Water out of a household faucet is best. Always flush
opposite the direction of air flow ie: from the clean side to the dirty
side. This removes the dirt and does not drive it further into the filter
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.
8. OILING PRECAUTIONS
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 othertype 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.
9. SPRAY OILING
Spray K&N Air Filter Oil from a distance of about 10
inches onto a group of pleats. Spray each group of pleats only once. Spray
oil onto the filter media such it becomes reddish in color. Let the filter
sit for 10 minutes then respray any areas that are still white.
10. SQUEEZE BOTTLE OR TUBE OILING
Squeeze K&N Air Filter Oil onto each pleat. Let the
filter sit for 20 minutes as the oil “wicks” into the surrounding
filter media. Apply more Filter Oil to areas that are still white
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
