How often should I clean and re-oil my K&N air filter?

The cleaning interval depends on your driving conditions. In normal conditions, clean the filter every 50,000 miles. If you drive in dusty or off-road conditions, you'll want to clean it more often.

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 the filter after cleaning. Regular motor oil will clog the filter and reduce airflow. K&N filter oil is designed to be sticky enough to trap dirt without restricting airflow.

What is the warranty on K&N air filters?

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 does not cover damage caused by misuse, abuse, or improper cleaning.
