Using your K&N replacement panel air filter is a breeze. First, locate your factory air box under the hood of your 2016 - 2022 Honda HR - V. Open the air box, remove the old air filter, and simply drop in the new K&N filter. Make sure it's properly seated and close the air box. As for maintenance, since the filter is washable and reusable, you don't need to replace it often. Check the filter regularly, about every 12,000 - 15,000 miles or once a year, depending on your driving conditions. If it looks dirty, wash it with a mild detergent and warm water. Let it dry completely and re - oil it using K&N filter oil before reinstalling. Keep in mind to always follow the vehicle's maintenance schedule and if you notice any issues with the filter or your vehicle's performance, consult a professional mechanic.
