How often should I clean and re-oil my K&N air filter?

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter regularly and cleaning it when you see a buildup of dirt and debris. A good rule of thumb is to clean it every 25,000 to 50,000 miles under normal driving conditions.

What kind of oil should I use to re-oil my K&N air filter?

You should only use K&N filter oil to re-oil your air filter. Using other oils can damage the filter media and reduce its effectiveness. K&N filter oil is specially formulated to work with the cotton media in the filter.

Does this air filter come pre-oiled?

Yes, this K&N air filter comes pre-oiled and ready to install. You don't need to oil it before installation. Just drop it into your factory air box and you're good to go.
