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

The cleaning interval depends on your driving conditions. K&N recommends cleaning the filter when the dirt buildup becomes visible on the media. In normal conditions, this is usually every 50,000 miles. Off-road driving will require more frequent cleaning.

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

K&N sells a Recharger Kit that includes both the cleaner and the oil you'll need. The cleaner removes dirt and old oil, and the oil restores the filter's ability to trap contaminants and improve airflow. Follow the instructions included with the kit for best results.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. You don't need to oil it before the initial installation. Just drop it in your factory airbox, and you're good to go.
