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

K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use. If you drive in dusty conditions, you may need to clean it more often. Regular cleaning ensures optimal airflow and performance.

Do I need to buy special oil to recharge the filter?

Yes, you'll need K&N filter oil to re-oil the filter after cleaning. This oil is specifically designed for the cotton gauze material and helps trap dirt and debris. Using the correct oil ensures proper filtration and prevents damage to the filter.

Will this filter void my car's warranty?

In most cases, no. Using a K&N replacement air filter will not void your vehicle's warranty under the Magnuson-Moss Warranty Act. This act protects consumers from warranties being voided due to the use of aftermarket parts, unless the part is proven to be the direct cause of a failure.
