Using your K&N air filter is a breeze. First, locate your factory air box. Open it up and carefully remove the old air filter. Then, place the K&N drop - in filter into the air box in the same position as the old one. Make sure it fits snugly. When it comes to maintenance, check the filter regularly. If it looks dirty, you can wash it. Use a mild cleaner and water to gently clean the filter. After washing, let it dry completely before applying the K&N filter oil. Don't over - oil it, as this can cause issues. Remember, this filter is designed to last the life of your vehicle, but proper care will keep it performing at its best. Keep it away from sharp objects to avoid damage.
