Using this Dress Up Bolts Engine Cover Kit is easy. Just follow the detailed installation instructions that come with the kit. First, make sure your Nissan 370Z (2009 - 2019) Z34 engine is turned off and cooled down. Then, carefully remove the old engine cover fasteners and replace them with the new Titanium ones from the kit. When choosing a color, pick the one that suits your style. As for maintenance, keep the fasteners clean. You can use a soft cloth to wipe them down regularly. Avoid using harsh chemicals as they might damage the Titanium finish. Also, check the tightness of the fasteners from time to time to ensure they stay secure.
