Drive Shaft / Center Tunnel Heat Shield – 4K1804164E

Original chassis / center tunnel heat shield (aluminum heat shield for the drive shaft and exhaust system), designed for Audi A7 Sportback (4K / 4K8 generation) and Audi A6 (C8 / 4K generation) models with 3.0 TFSI V6 (55 TFSI), 3.0 TDI engines and quattro all-wheel drive.

Original VAG heat insulation component made of profiled, stamped aluminum. It protects drivetrain components, the drive shaft, and the passenger cabin floor from direct heat radiation emitted by the heated exhaust system and particulate filters / catalytic converters.

Fitment guarantee and VIN verification

Each heat shield undergoes a geometry inspection to check for deformations, the condition of the mounting holes, and the cleanliness of the surface reflecting heat radiation.

Fitment tip: The 4K1804164E shield is a component of the sectional soundproofing and thermal shielding of the chassis tunnel. Before purchase, we recommend comparing the OE number stamped on the old shield or verifying compatibility using the vehicle's VIN.
