Using your K&N drop - in air filter is easy. First, make sure your car's engine is off and cool. Open the factory air box and remove the old air filter. Then, simply place the K&N filter in the same spot where the old one was. Close the air box, and you're good to go. As for maintenance, you don't need to replace the filter often. It's washable and reusable. When it gets dirty, you can clean it with a K&N filter cleaning kit. Follow the instructions on the kit to wash and re - oil the filter. Just remember to let it dry completely before putting it back in your car. Also, always keep an eye on your vehicle's performance. If you notice any issues, check the filter to make sure it's working properly. With proper use and maintenance, your K&N air filter will serve you well for the life of your vehicle.
