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

The cleaning interval depends on your driving conditions. K&N recommends cleaning and re-oiling your filter every 50,000 miles for normal highway use, but more frequent cleaning may be needed in dusty conditions. Use a K&N filter cleaning kit to properly service the filter.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. You do not need to oil it before installation, but you will need to re-oil it after cleaning.

Will this filter void my vehicle's warranty?

In most cases, no. Using a K&N air filter will not void your vehicle's warranty under the Magnuson-Moss Warranty Act. This act prevents a manufacturer from voiding a warranty due to the use of aftermarket parts unless they can prove the part caused the failure.
