AUTOID TRE Pre-Preg Carbon Fibre Shark Fin Antenna/Aerial Cover for BMW F & G Chassis (1/2/3/4/5 Series, X Models; incl. 335i, 340i, M2, M3, M4) - OEM Fit, No Signal Loss

AUTOID TRE Dry Carbon Roof Aerial Cap for BMW F and G Platform

Give your BMW a genuine OEM plus finish with this autoclaved dry carbon roof aerial cap from AUTOID. Crafted from a single layer of true pre-preg carbon for razor-sharp weave clarity and ultra-light rigidity, this elegant overlay slips neatly over the existing roof fin and elevates the entire rear roofline with a subtle motorsport look. Radio, DAB, GPS and Bluetooth reception stay intact, so you get the style upgrade without compromising day-to-day usability.

Compatible across a wide range of BMW F and G platform vehicles including 1 Series, 2 Series, 3 Series, 4 Series, 5 Series and X models, plus enthusiast favourites such as 335i, 340i, M2, M3 and M4. If your car has the standard roof fin, this carbon aerial shell is designed to fit over it for a clean, factory-style result.

Why this upgrade belongs on your BMW

• Autoclaved pre-preg carbon construction for a premium, factory-style aesthetic
• Single-layer design keeps DAB, FM, AM, GPS and Bluetooth performance unchanged

• Quick DIY install with pre-fitted 3M automotive adhesive, no tools required
• Pairs perfectly with carbon mirror caps, splitters, spoilers and rear diffusers
• Backed by a 2-year warranty from AUTOID

We run this piece on our own cars and customer feedback has been consistently positive on the finish, weave quality and ease of installation. If you are hunting for a BMW roof antenna cap, carbon aerial shell or fin trim for F chassis and G chassis cars, this is a top-tier choice that looks right at home on both daily drivers and track builds.
