How often should I clean this filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. Depending on conditions, you may need to clean it more often. Inspect the filter regularly and clean it when you see a buildup of dirt and debris.

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

You'll need a K&N filter cleaning kit, which includes both the cleaning solution and the filter oil. The cleaner removes dirt and grime, 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, this filter comes pre-oiled from the factory, ready to install. You do not need to oil it before its first use. You'll only need to re-oil it after cleaning.
