Using your K&N air filter is easy. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply place the K&N replacement filter into the air box, making sure it fits snugly. Close the air box and you're good to go. As for maintenance, every so often, check the filter for dirt and debris. When it's dirty, you can wash it with a mild soap and water. Let it dry completely and re - oil it using K&N filter oil. This will keep your filter performing at its best. Remember to always follow the vehicle manufacturer's guidelines when working on your car. And if you have any questions, don't hesitate to contact K&N's customer service.
