Purpose and function of the side vent window

The presented window has been designed specifically for the rear section of the body on the left side of the BMW E46 Coupe series, where it serves as a side vent window. Its design supports proper air circulation in the cabin while stabilizing the structure of the side body section, working in conjunction with other glazing elements.

The green tint of the glass is an integral part of the factory optical configuration, reducing interior heating and improving passenger visual comfort. As a result, the window harmoniously blends with the vehicle's other windows, maintaining a consistent look for the entire side profile.

Performance parameters and fitment for BMW

As an element from the Car windows group, this rear left side vent window has been prepared for precise fitment to the factory mounting points in the coupe body. The appropriate edge profile and correct surface geometry allow for proper seating in the frame and compatibility with the seals and fittings intended for this model.

Its original BMW origin helps maintain factory standards of rigidity, tightness, and compatibility with the existing body structure. This solution is particularly beneficial for accident repairs, replacing a damaged window, or restoring the vehicle to its original manufacturer specifications.

Glass characteristics and operational benefits

The green-tinted glass used belongs to the class designated as AS2, which in practice means it meets specific requirements regarding light transmission and operational safety. This type of side vent window supports protection against excessive sunlight while maintaining proper clarity and visibility of the surroundings.

This solution is particularly beneficial in daily use because it:

• reduces heating of the rear passenger cabin,
• supports thermal comfort during longer trips,
• maintains a consistent, factory look of the side window line in the BMW E46 Coupe.

Component condition and use in repairs

The window comes from the used BMW components market, making it an attractive solution for repairs where maintaining original specifications while optimizing costs is important. A used element from this group allows for the restoration of full functionality to the rear side glazing area without the need to use replacements with uncertain fitment.

In case of doubts regarding the selection of the appropriate window for a specific body configuration, it is worth verifying compatibility with the OEM number and interchangeable numbers in the technical specifications section to ensure full compatibility with the specific vehicle unit.
