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

Do I need to oil the filter after cleaning?

Yes, K&N air filters use a specially formulated oil to help trap dirt and improve airflow. After cleaning, you must re-oil the filter with K&N filter oil to maintain its performance. Use only K&N filter oil to avoid damaging the filter.

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 into your factory airbox and you're good to go.
