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

K&N recommends cleaning your filter every 50,000 miles, depending on your driving conditions. Inspect the filter regularly and clean it more often if you drive in dusty or dirty environments. A dirty filter restricts airflow and reduces performance.

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

You'll need a K&N air filter cleaning kit, which includes a cleaner and filter oil. The cleaner removes dirt and grime from the filter, and the oil restores the filter's ability to trap contaminants. Follow the instructions included with the cleaning kit for best results.

Does using a K&N air filter void my vehicle's warranty?

Using a K&N air filter will not void your vehicle's warranty, thanks to the Magnuson-Moss Warranty Act. This act prevents manufacturers from voiding a warranty simply because aftermarket parts are used.
