How often should I clean my K&N air filter?

K&N recommends cleaning your filter every 50,000 miles, depending on driving conditions. Inspect the filter regularly, and clean it more often if you drive in dusty or off-road conditions. A dirty filter restricts airflow and reduces performance.

What do I need to clean and re-oil my K&N air filter?

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

Does this filter come pre-oiled?

Yes, the K&N air filter comes pre-oiled and ready to install. You do not need to oil it before the initial installation. Just drop it in and you're good to go.
