Using these hood struts is a breeze. First, make sure your car is parked on a flat surface and the engine is cool. Then, install the struts with the simple pop - off, pop - on method, and bolt them on. Remember to place the carbon fiber part towards the top. These struts are not for use with carbon fiber hoods. When it comes to maintenance, just give them a regular visual check to ensure there are no signs of damage or wear. If you notice any issues, it's best to replace them right away. You can also clean them with a mild car cleaner to keep them looking good. Enjoy the convenience of easy - opening hoods with these Noble struts!
