Engine covers and engine bay dress-up components transform the underhood appearance of street cars, show builds, and muscle car restorations by replacing factory plastic engine toppers, air cleaner assemblies, and exposed wiring with billet aluminum, carbon fiber, and anodized covers that project a finished, custom look.
