How often should I clean and re-oil 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. Use K&N filter cleaner and oil to maintain the filter's performance.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled from the factory, so it is ready to install right out of the box. You don't need to oil it before the initial installation. Just drop it in and go.

Will this filter void my vehicle's warranty?

In most cases, installing a K&N air filter will not void your vehicle's warranty. K&N stands behind its products and the Magnuson-Moss Warranty Act protects consumers from voiding their warranty due to aftermarket parts, unless the part is proven to be the cause of a failure.
