Horn rearview mirror shell replacement kit for BMW 3 Series E90 2006-2012 models

This product is a direct replacement housing, or shell, for the exterior rearview mirrors on the BMW 3 Series E90. It is designed specifically for vehicles produced between 2006 and 2012, a period which is split into two distinct fitment groups: models from 2006 to 2008 and those from 2009 to 2012. The shell covers the internal mirror mechanism, providing the finished exterior look of the mirror assembly. Supplied as a complete pair, this kit allows you to refresh both mirror housings simultaneously, ensuring a uniform appearance. The shells are crafted from ABS plastic, a material selected for its balance of strength, lightweight properties, and suitability for precise automotive moulding. Owners can choose between a standard black finish or a carbon fibre pattern, offering a straightforward restoration option or a subtle stylistic change.

Features and Construction

This replacement shell kit is defined by its model-specific design and practical construction. It addresses the need for an exact fit on the BMW E90 platform, with clear options to match your vehicle's production year.

Material and Build

The housing is constructed from ABS plastic. In automotive applications, ABS is valued for its rigidity and impact resistance, making it a common choice for exterior trim pieces that must withstand minor knocks and environmental exposure. The material also provides a stable base for the applied finishes—whether the solid black or the carbon pattern—ensuring the colour and texture adhere properly and remain consistent. This construction offers a direct replacement for the original part, replicating its form and function.

Size and Practical Fit

Critical to its function is the precise fitment, which is governed by the original BMW part numbers. For the 2006-2008 E90 models, the shells correspond to OE numbers 51167135098 and 51167135097. For the updated 2009-2012 models, the correct references are 51167205291 and 51167205292. This clear division ensures purchasers can select the kit that will align correctly with their vehicle's mirror mounting points and contours. The product is supplied as one pair, meaning both the driver's side and passenger's side housings are included, which is essential for a symmetrical repair or upgrade.

Uses and Placement

The primary use for this product is the restoration or customisation of the exterior mirrors on a BMW 3 Series E90. It serves a clear functional role in vehicle maintenance and personalisation.

Event or Professional Use

For professional detailers, body shops, or enthusiasts preparing a vehicle for shows or resale, replacing faded, scratched, or damaged mirror housings is a recognised method to significantly improve a car's exterior presentation. This kit provides a cost-effective alternative to sourcing original manufacturer parts, while still offering a model-correct appearance. The choice of a carbon pattern finish can also be selected for vehicles where a sportier aesthetic is desired, aligning with common aftermarket styling themes.

Everyday Home Use

For the everyday owner, this product solves the practical problem of a broken or deteriorated mirror shell. Damage can occur from accidental impacts, weathering, or vandalism. A cracked or loose housing can look unsightly and may even expose the internal mirror components to moisture. This replacement kit allows a DIY-savvy owner to rectify such issues without the expense of a full mirror assembly replacement. The straightforward 'replacement installation' method indicates it is designed to fit onto the existing mirror base, making it a manageable project for many.

Benefits and Buying Value

The value of this product lies in its specificity, completeness, and the practical benefits of a simplified repair process for a common vehicle model.

Reuse and Low Maintenance

The kit leverages the existing, undamaged mirror mechanism and mounting hardware from the car. By reusing these core components, it offers an economical path to repair compared to replacing the entire mirror unit. Once installed, the ABS plastic shell requires minimal ongoing maintenance; routine washing with the rest of the car is sufficient. Its construction is designed for long-term exterior use, meaning it should not require frequent attention or special care beyond general vehicle cleaning.

Why Choose This Product

Choosing this product is justified by its direct application to a popular vehicle model with clear, verified part number matching. The inclusion of both left and right housings in the kit provides full coverage for the repair job. The availability of two finishes gives the owner a degree of personalisation within an OEM-style framework. Furthermore, the packaged dimensions (27x20x15 cm) and weight (500g) indicate a compact product that is straightforward to ship, store, and handle during the installation process, reducing logistical friction for the buyer.
