Purpose and function of the element

This shark fin roof antenna cover was designed specifically for the BMW X3 E83 series facelift (E83N LCI). It's a centrally mounted top antenna cover on the roof, protecting the antenna module and providing a consistent finish to the bodywork. The factory design ensures full compatibility with the original mounting point and roof moldings.

Color and visual matching

The part is painted in Highland Green Metallic – A11, allowing it to aesthetically match vehicles with the same factory color. The metallic coating provides a distinctive depth of color and complements the SUV's body lines, minimizing the need for additional painting when replacing a damaged housing with a part in the same color.

Original origin and performance parameters

The housing comes from a BMW, ensuring the factory dimensions, shape, and material quality are maintained. This is a used part with low mileage, which translates to limited mechanical and visual wear. The original mounting brackets and housing geometry facilitate installation in place of the factory antenna without requiring any body modifications.

Benefits of using the original antenna housing

• Factory fit – maintaining the correct roof profile and tightness at the installation site.
• Color consistency – Highland Green Metallic – A11 paint minimizes shade differences from the rest of the body.
• Antenna module protection – a solid cover protects the interior of the antenna from weather conditions.
• Exterior aesthetics – the distinctive “shark fin” highlights the roofline and maintains the original look of the BMW X3.

Why is it worth choosing a used part?

Choosing an original, used roof antenna housing is a sensible compromise between cost and quality. You get an OEM part with the correct shape, color, and fit, without the risks associated with aftermarket parts of dubious origin. For body parts like antenna housings, precise dimensions and roofline alignment are crucial – this is precisely what a component sourced from the original vehicle ensures.
