Using your K&N air filter is a breeze. First, locate your factory air box. Open it up and take out the old air filter. Then, simply drop in your new K&N air filter. Make sure it fits snugly and close the air box. You're good to go! As for maintenance, the filter is washable and reusable. When it gets dirty, which you can tell by a significant drop in performance or a visibly dirty filter, remove it from the air box. Wash it gently with a mild detergent and water. Rinse thoroughly and let it dry completely. After that, apply the K&N filter oil evenly to the media. This helps it capture contaminants effectively. When it comes to storage, keep the filter in a clean, dry place. Avoid storing it in direct sunlight or in areas with extreme temperatures. And remember, this filter is backed by K&N's 10 - Year/Million Mile Limited Warranty, so you can have peace of mind while using it.
