How often should I clean my K&N air filter?

The cleaning interval depends on your driving conditions. K&N recommends inspecting your filter every 25,000 to 50,000 miles and cleaning it when you see a buildup of dirt and debris. Off-road driving requires more frequent cleaning.

What do I need to clean and re-oil my K&N air filter?

K&N sells a Recharger Kit that includes both the cleaner and the oil you'll need. Follow the instructions included with the kit to properly clean and re-oil your filter. Allow the filter to dry completely before re-oiling.

Does this filter require oiling?

Yes, this is an oiled cotton gauze filter. It arrives pre-oiled, but you must re-oil it after each cleaning. The oil is what traps the dirt and allows the filter to still flow a high volume of air.
