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.

Do I need to oil this filter?

Yes, this K&N air filter uses a specially formulated oil to help trap dirt and contaminants. The oil is what makes the cotton gauze so effective at filtration. You'll need to purchase a K&N filter cleaning and oiling kit separately to maintain the filter.

What is the warranty on this K&N air filter?

This K&N air filter is backed by K&N's 10-Year/Million Mile Limited Warranty. This means K&N will replace the filter if it's defective in materials or workmanship. Keep your receipt as proof of purchase.
