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

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter regularly and cleaning it when you see a buildup of dirt and debris. Under normal conditions, this might be every 25,000 to 50,000 miles.

Do I need to oil the filter after cleaning?

Yes, K&N air filters use a special oil to help trap dirt and improve airflow. After cleaning, you'll need to re-oil the filter with K&N filter oil to maintain its performance.

What is the warranty on this K&N air filter?

K&N warrants its air filters to be free from defects in material and workmanship for 10 years or 1,000,000 miles. This warranty applies when the filter is properly installed and maintained.
