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. Use a K&N filter cleaning kit to maintain the filter's performance.

Does this filter require oiling?

Yes, this K&N air filter uses a specially formulated oil to help trap dirt and contaminants. The oil is part of what allows it to filter so well while still allowing good airflow. You'll need to re-oil it after cleaning.

Is there a warranty on this air filter?

Yes, K&N provides a 10-Year/Million Mile Limited Warranty for this air filter. This means K&N warrants that the filter will perform properly for up to 10 years or 1 million miles, whichever comes first.
