Properly selected guides and working elements ensure smooth flap movement, and the design of the filler recess facilitates correct seating of the fuel cap and convenient access to the filler neck during refueling.

The original Porsche origin helps maintain visual and technical consistency with other body components, minimizing the risk of fitment issues or leaks within the filler area.
