How often should I clean this filter?

K&N recommends cleaning and re-oiling your filter every 50,000 miles under normal highway driving conditions. Depending on your environment, you may need to service 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?

K&N sells filter cleaning and oiling kits specifically for this purpose. These kits contain a cleaner to dissolve dirt and grime, and a special oil to restore the filter's ability to trap contaminants. Using the correct oil is important to maintain the filter's performance.

Does this filter come pre-oiled?

Yes, this K&N filter comes pre-oiled and ready to install. The oil is what traps the dirt and debris, so it is important to maintain the oil level when you clean and re-oil the filter.
