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

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. Depending on your driving conditions, you may need to service it more often. Inspect the filter regularly and clean it when you see excessive dirt or debris.

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

You'll need a K&N filter cleaning kit, which includes both the cleaner and the oil. The cleaner removes dirt and grime from the filter, and the oil restores the filter's ability to trap contaminants and improve airflow. Follow the instructions included with the cleaning 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 its first use. Just drop it into your factory air box and you're good to go.
