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

K&N recommends cleaning your filter every 50,000 miles for normal highway use. If you drive in dusty conditions, you may need to clean it more often. Regular cleaning ensures optimal airflow and performance.

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, while the oil recharges the filter's ability to trap contaminants. Follow the instructions on 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 do not need to oil it before the initial installation. Just drop it in and you're good to go.
