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

K&N recommends cleaning and re-oiling your filter every 50,000 miles under normal driving conditions. If you drive in dusty or off-road conditions, you may need to clean it more frequently. Regular cleaning ensures optimal airflow and 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 air filter cleaner and air filter oil. The cleaner removes dirt and grime, while the oil restores the filter's ability to trap contaminants and improve airflow. Follow the instructions on the cleaning kit for best results.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. You don't need to oil it before the initial installation. Just drop it into your factory air box, and you're good to go.
