How To Clean K&N Air Filters

---

1. APPLY CLEANER
Liberally spray K&N Air Filter Cleaner 99-0606 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.

 

2. RINSE 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.

 

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


4. OIL FILTER
Aerosol Oil (99-0504)

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.
