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

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter every 25,000 miles and cleaning it when you see a buildup of dirt and debris. Off-road driving requires more frequent cleaning.

Do I need to oil the filter after cleaning?

Yes, K&N air filters must be oiled after cleaning to maintain their filtration properties. Use K&N filter oil and apply it evenly to the filter media. Oiling the filter ensures proper airflow and particle capture.

What kind of warranty does this filter have?

This K&N air filter is backed by K&N's 10-Year/Million Mile Limited Warranty. This means K&N will replace the filter if it's defective in materials or workmanship. Be sure to register your filter on the K&N website to activate the warranty.
