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

Do I need to buy special oil to recharge the filter?

Yes, you'll need K&N filter oil to re-oil the filter after cleaning. This oil is designed to work with the cotton gauze material and ensure proper filtration.

What kind of warranty does this air filter have?

This K&N air filter is backed by K&N's Million Mile Limited Warranty. This means K&N warrants that the filter will perform for the life of your vehicle, provided it is properly cleaned and re-oiled.
