Original Styrofoam Trunk Insert / On-Board Tool Organizer – 4K8012127A

Original factory-fit styrofoam trunk floor / spare wheel well insert (emergency kit, jack, tow eye, and compressor organizer – Werkzeugeinsatz / Schaumstoffeinlage Kofferraum), designed for Audi A7 Sportback, S7, and RS7 (4K / 4K8 generation) models produced from 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI / 340 hp), 2.0 TFSI (40/45 TFSI), S7 and RS7 variants, and TDI diesel engines, based on the MLBevo modular longitudinal platform.

Original VAG factory-fit trunk equipment component. Made of hardened, high-density expanded polypropylene / polystyrene (EPP/EPS), combining very low weight with high mechanical resistance to pressure, moisture, and automotive chemicals. Revision 4K8012127A features an optimized layout of recesses for the factory Audi tool kit (screw jack, wheel wrench, tow eye, screwdriver, and wheel nut socket pliers) and provides space for electrical installation / battery components in versions with the Mild Hybrid (MHEV) system. It provides stable, factory-fit support for the movable trunk floor panel and effectively eliminates tool rattling on uneven roads.

Fitment guarantee and VIN verification

Each insert undergoes a thorough structural integrity inspection to check for load-bearing cracks and a slot cleanliness check before shipping.

Fitment / installation note: The initial 4K8 designation (emergency equipment group 012) with index A defines an insert precisely contoured to the body floor panel recesses of the new-generation Audi A7 Sportback. Versions with the “A” index account for the specific routing of high-current wiring harnesses and the 12V/48V battery cover in the trunk. Using an incorrect insert or no insert causes the floor panel to sag under the weight of the cargo and creates unpleasant noise from loose tools rattling against the metal. The original OEM insert ensures a perfectly flush fit. Before purchasing, we recommend comparing the OE number stamped directly onto the styrofoam or verifying it using the vehicle's VIN.
