Purpose and fitment for BMW X5 E70

The presented side window has been designed specifically for the rear left body section of the BMW X5 E70, ensuring correct geometry, the appropriate tilt angle, and compatibility with factory seals and trim. The triangular shape of the glass allows for precise fitting into the body frame, without the need for modifications or adjustments required by aftermarket replacements.

Its original BMW origin ensures that factory safety and quality standards are maintained, including the correct thickness, layer structure, and compliance with the AS3 standard for tinted glass.

Characteristics of AS3 tinted glass

The AS3 tinted side window in the rear part of the vehicle serves several important functional and visual purposes:

• reduction of light penetration and limitation of interior vehicle heating,
• increased privacy for passengers in the rear seat,
• a consistent, darker appearance of the side window line, characteristic of versions with factory tinting,
• protection of upholstery and plastic elements against excessive UV radiation.

The color specified as Black, combined with the tinting, creates a harmonious visual effect, especially when paired with dark door frames and body pillars.

Vehicle placement and installation aspects

The glass is intended for installation in the rear left body area as a fixed, triangular pane. This placement requires high dimensional accuracy to ensure:

• proper adhesion to seals and body components,
• no stress on the glass after installation,
• adequate sealing against water and external noise.

As an item from the Car windows category, the product is prepared for installation by a specialized glass service or body shop, using dedicated adhesives and mounting accessories selected for the specific BMW model.

Product condition and benefits of choosing used OEM parts

The item is offered as a used part, which allows for combining attractive repair costs with the preservation of the manufacturer's original specifications. In practice, this means:

• factory fitment to the BMW X5 E70 body,
• preservation of the original styling line and tint level,
• more predictable performance during operation compared to low-quality aftermarket replacements.
