Center Tunnel Heat Shield / Exhaust and Driveshaft Thermal Insulation Shield – 4K0804160E

Original center tunnel heat shield / underbody heat shield (thermal and acoustic insulation for the driveshaft tunnel and exhaust system), designed for Audi A7 Sportback, S7 and RS7 (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 (40/45 TFSI), TDI engines, and top-spec 2.9 TFSI (S7) and 4.0 V8 TFSI (RS7) models, based on the modular MLBevo longitudinal platform.

VAG factory underbody thermal insulation component. Made of multi-layer stamped technical aluminum with a heat-dissipating micro-embossed structure (Heat Shield). Mounted in the center tunnel of the floor pan, directly between the exhaust system / driveshaft and the vehicle body. It provides an effective thermal barrier protecting the interior floor, gear selector assembly, wiring harnesses, and driveshaft support bearing from heat radiation from the exhaust pipes and catalytic converters/particle filters, while also reducing underbody resonance noise.

Fitment guarantee and VIN verification

Every thermal shield undergoes a check of the mounting holes for metal retaining clips and a surface inspection for dents before shipping.

Fitment / installation tip: The base designation 4K0 804 160 E (chassis group 804) is the factory thermal shield protecting critical components from high exhaust temperatures. In used cars, corroded or torn mounting holes for star-shaped retaining clips are a common fault, causing the shield to sag and rattle against the driveshaft or exhaust. The offered component has intact mounting points, ensuring a secure and quiet fit. Before purchasing, we recommend comparing the OE revision letter stamped on the metal or verifying it using the vehicle's VIN.
