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 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 air filter cleaner and air filter oil. You spray the cleaner on the filter, rinse it off, let it dry, and then apply the oil. Refer to the instructions included with the cleaning kit for detailed steps.

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.
