Engine Covers
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. On modern high-performance vehicles including the Dodge Challenger, Charger, Hellcat, Trackhawk, Jeep Grand Cherokee, and Chevrolet Camaro and Corvette, factory valve covers and engine toppers are functional but visually uninspiring compared to what Billet Technology, Cordes Performance, and Anderson Composites produce for the same platforms. Classic and muscle car owners restoring small block Chevy, big block Chevy, Ford 289, 302, 390, and Chrysler 440 and HEMI engines find that chrome and polished aluminum valve covers, air cleaner kits, and timing chain covers complete the correct engine bay presentation for shows and driver quality restorations.
