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 buy special oil to re-oil the filter?

Yes, you'll need to use K&N filter oil to properly re-oil your air filter after cleaning. Regular motor oil or other oils are too thick and will damage the filter. K&N filter oil is specially formulated to work with the cotton media.

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 will replace the filter if it's defective in material or workmanship. The warranty does not cover damage from misuse or improper cleaning.
