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 is included in the K&N Million Mile Limited Warranty?

K&N warrants that their air filters will be free from defects in material and workmanship for one million miles or the life of the vehicle. This warranty covers the filter itself and protects your engine from damage caused by a defective filter.

Do I need to purchase oil separately to maintain this filter?

Yes, this filter requires special filter oil to maintain its filtration properties. K&N sells filter cleaning and oiling kits separately. Refer to the manufacturer's instructions for proper cleaning and oiling procedures.
