Right Trunk Foam Insert / Luggage Compartment Tool Box Insert – 4K0864476

Original right trunk floor foam insert (organizer / insert supporting the floor panel and providing a compartment for onboard tools and equipment), designed for Audi A7 Sportback (4K / 4K8 generation) and Audi A6 C8 (type 4K2 / 4K5 / 4KA) models produced from 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI), 2.0 TFSI, TDI engines, and Mild Hybrid (MHEV 48V) variants, based on the modular MLBevo longitudinal platform.

Original VAG luggage compartment trim element. Made of high-quality, reinforced expanded polypropylene (EPP) in black, featuring low weight, excellent resistance to mechanical deformation under load, and vibration and noise absorption properties. It is installed under the main cargo floor of the trunk on the right side (next to the spare wheel / battery compartment). It provides stable support for the trunk floor panel under heavy loads, preventing it from flexing, and also allows for the safe, rattle-free placement of service tools, the tow eye, compressor, or additional electrical system modules.

Fitment guarantee and VIN verification

Each insert undergoes a thorough inspection of the side walls, a check of the support geometry, and cleaning before shipping.

Fitment / installation tip: The base designation 4K0 864 476 is a structural element common to the MLBevo platform of Audi A6 C8 and A7 4K models. It precisely fills the technical space between the sheet metal floor and the moving trunk panel. Using the original EPP insert ensures that the trunk floor lies perfectly flat and does not creak or flex under the weight of transported luggage. Before purchasing, we recommend comparing the OE number stamped on the foam or verifying fitment using the vehicle's VIN.
