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 12 months or 12,000 miles and cleaning it when you see a buildup of dirt and debris. Off-road driving will 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 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.

Does this filter come pre-oiled and ready to install?

Yes, this K&N air filter comes pre-oiled from the factory, so it is ready to install directly into your vehicle's airbox. You don't need to do anything before installation.
