Most K&N Filters will normally require cleaning every 50,000 miles. Servicing your K&N Filter is simple; just follow the 4 easy steps below.
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.
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.
After rinsing, gently shake off excess water and only allow filter to dry naturally. Do not oil until the filter is completely dry.
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.
