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

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter every 25,000 miles and cleaning it when you see a buildup of dirt and debris. Off-road driving may require 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 air filter cleaner and the air filter oil. Follow the instructions included with the kit to properly clean and re-oil your filter.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. You do not need to oil it before the initial installation. You'll only need to oil it after cleaning.
