Using your K&N carbon fiber air box is straightforward. Install it in place of your old air intake system as per the vehicle's fitment instructions. When it comes to maintenance, check the filter regularly. If it looks dirty, remove it and clean it with K&N cleaner. Let it dry completely, then apply K&N oil evenly to the filter. This will ensure maximum air flow and filtration efficiency. Remember to always follow the safety guidelines when working on your vehicle. And if you have any questions, don't hesitate to reach out to K&N's customer service.
