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. Depending on your driving conditions, you may need to service your filter more often. Inspect the filter regularly and clean it when you see excessive dirt or debris.

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 media so effective at filtration while maintaining high airflow. A new filter is pre-oiled from the factory.

What kind of warranty does this air filter have?

This K&N air filter is backed by K&N's 10-Year/Million Mile Limited Warranty. This means K&N warrants that the filter will perform properly for up to 10 years or 1 million miles, whichever comes first.
