Purpose and fitment for BMW X3 F25
The presented window has been designed specifically for the BMW X3 F25 model, taking into account factory mounting points and the shape of the rear body section. Its placement on the rear left side of the vehicle allows for the precise recreation of the original side line, which is important for both aesthetics and the interior’s sealing and acoustics.
The component belongs to the Car windows category, meaning it meets the requirements for transparency, stress resistance, and compatibility with the seals and mounting trims intended for this model.
Technical characteristics and construction
The AS3 side window is prepared for operation in demanding conditions typical of the SUV segment. The black color used in the border area facilitates an aesthetic connection with the body paint and trim elements, while also masking the bonding and mounting zones.
Its placement in the rear left section of the vehicle promotes the maintenance of proper body structural rigidity and correct interaction with adjacent body panels. As a result, after proper installation, it is possible to achieve even gaps, proper seal pressure, and reduced noise in the cabin.
Condition, origin, and practical application
The offered window is a used component, which in practice allows for combining cost-effective repairs with maintaining the manufacturer’s original specifications. For many users and workshops, this is a reasonable compromise between purchasing a new part and cheaper replacements with uncertain fitment.
