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. Proper maintenance 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 filter cleaning kit, which includes both cleaner and oil. The cleaner removes dirt and grime, while the oil restores the filter's ability to trap contaminants and enhance airflow. Using the correct K&N products ensures the filter remains effective.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled from the factory, ready for installation. You can install it directly into your vehicle's airbox without any additional steps. Just make sure your vehicle is listed in the fitment data.
