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

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter regularly and cleaning it when you see a buildup of dirt and debris. In normal conditions, cleaning every 50,000 miles is typical.

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. Let the filter dry completely before re-oiling and reinstalling.

Does this filter come pre-oiled?

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