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

K&N recommends cleaning 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's 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 new car warranty. K&N backs this up with their warranty policy.

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.
