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 proper airflow and filtration.

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 'tacky' to catch particles. Use only K&N filter oil to avoid damaging the filter.

What is the warranty on this air filter?

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, provided it is properly installed and maintained.
