Purpose and function in the trunk

Thanks to its factory-fit design, the insert works with the original trunk floor, creating a cohesive, aesthetic, and practical storage system.

Construction and fitment for Mercedes ML W166

The item belongs to the Linings, trim strips, and decorations group, which means that beyond its functional role, it also serves an aesthetic purpose in the trunk compartment. The shape and geometry are adapted to the body architecture of the ML W166, allowing the insert to:

• precisely fill the space around the spare wheel,
• provide stable support for the trunk floor,
• minimize the risk of unwanted play and rattling while driving.

Its original Mercedes origin ensures compatibility with factory mounting points and consistency with other interior trunk trim elements.

This solution is particularly useful for users who frequently use their cargo space – both for daily city driving and during longer trips.
