Instructions for using the K&N Air Filter Cleaning Kit:
1. APPLY CLEANER
FOLLOW ALL SAFETY INSTRUCTIONS ON THE K&N AIR FILTER CLEANER BOTTLE.
Spray K&N Air Filter Cleaner onto both sides of the air filter until it
completely saturates the pleated material.
A. Apply K&N Air Filter Cleaner to clean side of filter
B. Apply K&N Air Filter Cleaner to dirty side of filter
Allow cleaner to soak into both sides of air filter for 10 minutes to loosen the
dirt. Do not let cleaner dry on air filter.
CAUTION: THE USE OF ANY OTHER CLEANING SOLUTION OR METHOD COULD
DAMAGE THE FILTER!
Rinse off air filter with cool low-pressure water. Allow gravity to flush dirt out
of air filter by applying water to the clean side of the filter; up and down the
length of the pleats.
Continue to rinse the filter until all traces of cleaner are gone. If the filter is
extremely dirty it may be necessary to repeat steps 1 and
2. If there are
spots of dirt remaining on the filter, spray each spot directly with cleaner,
allow a few minutes for it to soak and repeat rinsing step.
After rinsing, gently shake off excess water and allow filter to dry naturally.
Do not proceed to the oiling step until the filter is completely dry.
CAUTION: THE USE OF ANY OTHER DRYING METHODS (I.E. COMPRESSED AIR,
DRYER HEATERS, HEAT GUNS) COULD DAMAGE FILTER.
RECOMMENDATION: FOR BEST RESULTS USE K&N AIR FILTER OIL.
Apply K&N Air Filter Oil liberally to the dirty side of the filter only. This will
allow for a visual reference of complete coverage.
A. If using a K&N squeeze bottle, squeeze bead of oil along the crown of
each pleat using the lip on the squeeze bottle tip as a guide. Utilize
graduated view strip on bottle to dispense proper amount of oil.
B. If using a K&N aerosol spray, spray an even amount of oil along the
crown of each pleat.
Wait 20 minutes for the oil to be absorbed into the filter media. Inspect the
clean side of the filter for any areas that are lighter in color. Touch up these
areas in the media by applying oil to the dirty side of the filter. Continue
oiling procedure until there is an even red color over the entire surface of
the clean and dirty side of filter.
5. FILTER INSTALLATION
Before reinstalling filter back into vehicle, inspect it for damage. Follow any
and all specific installation instructions that came with the K&N Air Filter.
