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

K&N recommends cleaning and re-oiling your filter every 50,000 miles under normal driving conditions. If you drive in dusty or off-road conditions, you may need to clean it more frequently. Use a K&N filter cleaning kit to properly clean and re-oil the filter.

Will this filter void my vehicle's warranty?

Using a K&N replacement air filter will not void your vehicle's warranty. K&N air filters are designed to meet or exceed OEM specifications, and the 10-Year/Million Mile Limited Warranty provides added peace of mind.

Does this filter come pre-oiled?

Yes, the K&N 33-5094 air filter comes pre-oiled and ready to install. You do not need to oil it before installation. Just drop it in the factory airbox, and you're good to go.
