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. A dirty filter restricts airflow, which hurts performance.

Do I need to oil this filter?

Yes, this K&N filter uses a specially formulated oil to help trap dirt and debris. The oil is what makes the cotton gauze sticky and able to capture smaller particles. You'll need to purchase a K&N filter cleaning and oiling kit separately to maintain the filter.

What is the warranty on this air filter?

K&N warrants its air filters to be free from defects in material and workmanship for 10 years or 1,000,000 miles. This warranty applies when the filter is properly installed and maintained. See the manufacturer's website for full details.
