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

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter every 25,000 to 50,000 miles and cleaning it when you see a buildup of dirt and debris. Use a K&N filter cleaning kit to properly clean and re-oil the filter.

Does this filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install in your vehicle's airbox. You don't need to oil it before the initial installation, but you will need to re-oil it after cleaning.

Will this filter void my vehicle's warranty?

Using a K&N replacement air filter should not void your vehicle's warranty. K&N air filters are designed to meet or exceed OEM specifications, and the Million Mile Limited Warranty provides added protection.
