Using your K&N Flow Control System is easy. First, install it in your vehicle following the included instructions. Make sure it's securely attached to ensure proper air intake. When using, just drive as you normally would and enjoy the improved performance. As for maintenance, check the filter element regularly. If it looks dirty, you can clean it with a K&N filter cleaning kit. Don't use harsh chemicals as they might damage the filter. Also, keep an eye on the custom base and lid for any signs of wear or damage. If you notice any issues, contact K&N customer service for advice.
