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

K&N recommends cleaning your filter every 50,000 miles for normal highway driving. Depending on your driving conditions, you may need to clean it more often. Inspect the filter regularly and clean it when you see a buildup of dirt and debris.

What do I need to clean and re-oil my K&N air filter?

You'll need a K&N air filter cleaning kit, which includes both the cleaner and the oil. The cleaner removes dirt and grime from the filter, and the oil restores the filter's ability to trap contaminants. Follow the instructions included with the cleaning kit for best results.

Does this 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 installing it in your vehicle. Just drop it in and you're good to go.
