Get that predator look on your BMW with the AutoTecknic vacuumed dry carbon fiber 'shark fin' antenna cover. Made with AutoTecknic's signature vacuum forming technology, our products offer perfect fit and finish every single time. All of our carbon fiber products are constructed with a consistent carbon weave pattern.
Our production processes allow for an exceptional pre-preg carbon/resin ratio, creating high product stiffness, leading to added strength and resistance. For a stunning finish, our products are coated with a high gloss, UV-resistant clear coat that resists yellowing and does not chip or flake.
We meticulously inspect all of our components before shipment and stand firmly by our products so that you can enjoy peace of mind with every genuine AutoTecknic carbon fiber product.
Note: The antenna cover will only affect XM signals; all other bands will not be affected. Not Compatible with 2023 LCI Models.
