How often should I clean this 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'll want to clean it more often. Regular cleaning ensures proper airflow and extends the filter's life.

What do I need to clean and re-oil the filter?

You'll need a K&N filter cleaning kit, which includes both the cleaner and the oil. The cleaner removes dirt and old oil, and the oil restores the filter's ability to trap contaminants. Follow the instructions on the kit for best results.

Is this filter street legal?

This filter is not CARB-approved, so it is not legal for street use in California. Check your local regulations for compliance.
