Using this Cobb Redline Fuse Cover is simple. First, refer to the installation guide that comes with the product. It will walk you through the steps to properly install the cover on your Subaru WRX or STI. When handling the fuse cover, be gentle as the carbon fiber is strong but can be damaged if mishandled. For maintenance, use a soft, dry cloth to wipe it clean. Avoid using harsh chemicals or abrasive materials as they can scratch the high - quality gloss finish. Keep it in a dry place when not in use to prevent any damage from moisture. If you notice any loose parts or issues during installation or use, don't hesitate to contact the support team.
