Transform the look of your BMW G80/G81 M3 or G82/G83 M4's engine bay with the Downstar Inc Deluxe Billet Engine Dress Up Kit, designed to bring premium detailing and precision craftsmanship to your S58-powered BMW. Featuring over 100 precision-machined components, this deluxe kit replaces your factory hardware with billet aluminium beauty washers and high-quality socket head bolts for a clean, refined finish that perfectly complements the G8X platform.
Each component is CNC-machined from 6061 billet aluminium and paired with your choice of blue zinc, gold zinc, or stainless steel fasteners, allowing you to achieve a custom look that reflects your personal style. The Deluxe Kit includes 16 additional pieces compared to the standard Downstar G8X kit, offering more coverage and detail across the entire front end and engine bay.
Every fastener location has been carefully mapped to ensure a perfect fit and easy installation, with detailed instructions included for a straightforward DIY experience. Designed and manufactured in the USA, this kit not only enhances aesthetics but also showcases Downstar’s renowned build quality and attention to detail.
