The antenna cover made of aramid fibre-reinforced plastic is an optical and functional highlight on the car roof. Due to the fact that aramid fibres and carbon fibres look extremely similar, this product completes the "carbon" look on cars with the carbon package or other carbon exterior components. The function of the antenna is maintained as aramid delivers high permeability for electromagnetic waves.Carbon, on the other hand, has a shielding effect and cannot be used for antenna covers. This is a brand new, genuine OE, M performance antenna / aerial cover to fit various models including G21 / G81 3 series, G22 / G82 4 series, F97 X3M, F98 X4M, F95 X5M, F96 X6M, G05 / G18 X5, G06 X6, G07 X7, G09 XM.
