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. If you drive in dusty conditions, you may need to clean it more often. Regular cleaning ensures optimal airflow and performance.

What kind of oil do I use to re-oil my K&N air filter?

You must use genuine K&N air filter oil to properly re-oil your filter after cleaning. Other oils may damage the cotton fibers or not provide adequate filtration. K&N filter oil is specially formulated to work with the cotton media.

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 its initial use. Just drop it in and you're ready to go.
