HOW TO CLEAN YOUR K&N AIR FILTER

K&N® OILED COTTON STOCK REPLACEMENT OR UNIVERSAL HIGH-FLOW AIR FILTER

If you have not experienced a decrease in mileage or engine performance, chances are your filter is fine and does not yet need cleaning. To be more specific, the filter does not require cleaning if you can still see the wire screen on the entire air filter regardless of how dirty it may appear. When the screen is no longer visible some place on the filter, it is time to clean it. When used in normal paved road, street or highway conditions, K&N replacement air filters that fit in the factory air box should require cleaning every 50,000 miles and K&N large conical filters on an intake system should require cleaning every 100,000 miles.

When used in dusty or off-road environments, K&N filters will require cleaning more often. Company recommend that you visually inspect your filter once every 25,000 miles to determine if the screen is still visible.

STEP 1 - APPLY K&N® POWER KLEEN®

Liberally spray K&N Air Filter Cleaner onto both sides of filter and allow to soak for 10 minutes to loosen the dirt. Do not allow cleaner to dry on air filter.

STEP 2 - RINSE YOUR FILTER WITH LOW PRESSURE WATER

Rinse off air filter with cool low-pressure water applied to the clean side out in order to flush the dirt out of the filter. Continue to rinse the filter until all traces of cleaner are gone. It may be necessary to repeat steps 1 and 2.

STEP 3 - ALLOW YOUR FILTER TO DRY NATURALLY

After rinsing, gently shake off excess water and only allow filter to dry naturally. Do not oil until the filter is completely dry.

STEP 4 - APPLY K&N® FILTER OIL

A) Squeeze Oil (KN-99-5050)

Apply K&N Air Filter Oil evenly along the crown of each pleat. Allow oil to wick for approximately 20 minutes. Touch up any light areas on either side of filter util there is a uniform fed color at all areas.

B) Aerosol Oil (KN-99-5000)

Spray K&N Air Filter Oil evenly along the crown of each pleat holding nozzle about 3" away. Allow oil to wick for approximately 20 minutes. Touch up any light areas on either side of the filter until there is a uniform red color at all areas. The above process is the only approved procedure for maintaining your K&N Air Filter.
