Purpose and fitment for BMW E90/E91

The cover is designed as an external mirror housing for the driver's side on BMW 3 Series E90/E91 models. The geometry of the component matches the factory mirror dimensions, which facilitates installation and guarantees proper adhesion to the housing. This ensures the body line is maintained and the mirror operates through its full range of adjustment without colliding with the casing.

Black Sapphire Metallic color and finish

The Black Sapphire Metallic finish (paint code 475) allows for a visually consistent restoration of the vehicle's original appearance. The metallic structure of the paint works well with factory BMW paintwork, minimizing shade differences when the bodywork is properly maintained. This is a particularly beneficial solution when replacing a single component after a minor collision or parking damage.

Design characteristics and installation

The mirror cover serves as an external shield for the housing, protecting the adjustment mechanism and the mirror glass from external factors. The component is prepared for installation in place of the factory housing, using existing mounting points on the mirror. Due to the preservation of the original geometry, it is possible to:

• restore the factory shape of the driver's side mirror,
• maintain proper airflow around the body in the mirror area,
• reduce housing vibration at higher speeds.

The component comes from disassembly, meaning it is a used part, but remains fully functional in terms of installation and operation.

Practical application and benefits of replacement

Replacing a damaged mirror cover with an original component from the same series allows you to restore the aesthetics of the side bodywork without the need to interfere with the adjustment mechanism or the mirror's electrical installation. This solution is particularly beneficial when:

• the factory housing has cracked or is deeply scratched,
• local repair is necessary after a side collision,
• you want to maintain a consistent look with the Black Sapphire Metallic paint.

The original mirror cover helps maintain the vehicle's value, as it preserves the factory styling line and does not require the adaptations characteristic of low-quality aftermarket replacements.

Operational safety and the condition of body components

Functional side mirrors, with properly installed covers, improve the comfort of observing the vehicle's surroundings and reduce the risk of additional damage to the adjustment mechanism. It is worth remembering that similar selection principles apply to other components, especially in the area of active safety.
