Product description
Koshi carbon fuel flap cover Alfa Romeo Giulia
The exterior fuel flap forms a separate surface on the Alfa Romeo Giulia’s side. Koshi ARGL-21 gives that area a carbon finish. The pictured cover has a rounded rectangular outline and gently curved upper surface, corresponding to the illustrated fuel-flap shape.
Carbon on the exterior flap
Exposed weave runs across the broad centre and rounded corners. The finish concentrates on the flap that gives access to the filler opening. The original flap forms the base for this shaped exterior component, defining the carbon’s position in the side profile.
Prepreg carbon OEM overlay
Koshi describes ARGL-21 as a cover over the original OEM part. The manufacturer uses 0.6 mm prepreg carbon cured in an autoclave and finished with high-gloss clear lacquer. This article is the exterior flap cover; the internal filler cap and sealing mechanism are different components. Its shape and ARGL-21 article code identify this Giulia version.
