Application and vehicle fitment

The presented window is designed for installation in the front left door of the Audi A4 B7 generation. The placement on the vehicle is factory-defined as the front driver's side, which guarantees the correct geometry, shape, and bending radius of the glass relative to the door frame and seals.

Due to its design in accordance with the manufacturer's specifications, the component works with the factory window regulator, tracks, and seals, which translates into stable window operation during opening and closing, as well as reduced noise and vibration in the cabin.

• adequate visibility in various lighting conditions,
• a controlled level of radiation filtration,
• proper compatibility with mirrors and other vehicle windows.

Choosing a window of the correct class is important for both driving safety and the comfort of the driver and passengers.
