Product description
Koshi carbon antenna cover Alfa Romeo Giulia Stelvio
The shark-fin antenna is a small but recognisable detail on the roof of the Alfa Romeo Giulia or Stelvio. Koshi ARGL-20 adds an exposed carbon outer layer to this antenna. Its shell follows the broad curved base and narrows towards the top, matching the profile shown in the product image.
A carbon detail on the roof
The dark weave extends around the sloping antenna profile. From the side, the rising fin shape remains the main feature; from behind, the narrow upper section provides the accent. The cover therefore concentrates its carbon finish on a clearly defined roof detail.
Overlay on the original antenna
Koshi describes ARGL-20 as a cover over the original OEM component. The existing antenna remains underneath; the supplied component provides the exterior finish. The manufacturer uses 0.6 mm prepreg carbon cured in an autoclave. High-gloss clear coat reveals the weave across the curved surfaces. This article is the shaped shark-fin cover for the pictured Giulia and Stelvio antenna.
