Purpose and function of the side vent window

The presented side vent window has been designed specifically for the rear right side of the BMW E46 Coupe body. It is a fixed glazing element responsible for illuminating the interior, improving visibility, and providing structural stability to the side area of the body. The applied green tint helps reduce cabin heating while maintaining image clarity and driving comfort.

As a part from the Car Windows group, this element works in conjunction with the vehicle's other windows to create a uniform, sealed, and functional glazing system. A correctly selected side vent window is important for both passive safety and daily vehicle comfort.

Performance parameters and fitment for the BMW E46 Coupe

The glass has been manufactured to standards meeting BMW requirements for the coupe body, maintaining the appropriate geometry, thickness, and glass grade. As a result, it ensures:

• precise fitment to the body frame on the rear right side,
• stable seating in seals and mounting elements,
• proper compatibility with factory trims and fittings,
• preservation of the factory side line and the characteristic silhouette of the E46 Coupe.

The green tint is consistent with the typical factory tint used in this model, which allows for the aesthetic replacement of a single element without the need to interfere with the other windows. This is particularly important for post-accident repairs or replacing a damaged window, where the visual consistency of the entire glazing is essential.

Glass characteristics and technical aspects

The green version of the side vent window belongs to the glass class designated as AS2, which in practice means an appropriate level of light transmission and compliance with homologation requirements for side windows. This type of glass is designed to:

• ensure good visibility in various lighting conditions,
• limit excessive heating of the vehicle interior,
• work with factory seals and frames,
• maintain appropriate mechanical strength during daily use.

By maintaining factory glass parameters, replacing a damaged element with this window allows for the restoration of the vehicle's original performance and visual properties, without the need for body or mounting element modifications.

Condition, origin, and benefits of choosing used OEM glass

The offered glass comes from a BMW vehicle and is a used component, which allows for combining reasonable repair costs with the preservation of the original manufacturing standard. In practice, this means the customer receives a part with factory geometry and fitment, while reducing expenses compared to purchasing a new element.

Rising service costs mean that proven used parts are increasingly being chosen, especially for body and glazing components.
