Using your Noble Platinum Dry Carbon Fiber Under - Hood Fuse Box Cover is easy. First, make sure your engine is cool. Then, remove the factory fuse box cover. Since the new cover comes with pre - applied 3M adhesive, simply align it with the fuse box and press it firmly into place. As for maintenance, clean it with a soft, dry cloth regularly. Avoid using abrasive cleaners as they might scratch the gloss clear coat finish. When you're working around the engine, be careful not to bump or drop anything on the cover to prevent damage. That's all you need to know to keep your cover looking great and functioning well.
