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. Use a K&N filter cleaning kit to properly service the filter.

Does this filter come pre-oiled?

Yes, the K&N 33-2129 air filter comes pre-oiled and ready to install. You don't need to oil it before the initial installation. Just drop it in the factory airbox.

Will this filter void my vehicle's warranty?

Using a K&N replacement air filter will not void your new car warranty, according to K&N. The filter is designed to meet or exceed OEM specifications without causing harm to the engine or emissions system.
