Left Fender Liner 4K8821169 Audi A7 S7 RS7 4K Soundproofing OE

Left Front Fender Cover / Wheel Arch and Fender Sound Insulation – 4K8821169

Original inner cover / soundproofing and sealing insert for the left front fender (internal soundproofing for the fender wheel arch / acoustic cover for the A-pillar and wheel arch area on the driver's side), 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), 2.0 TFSI, TDI engines and top-spec S/RS models based on the modular MLBevo longitudinal platform.

Original VAG bodywork insulation and protective component. Made from a special compressed technical plastic combined with high-density sound-absorbing material, resistant to moisture, road salt, temperature changes and dirt. Mounted inside the left front fender structure (between the outer fender panel, wheel arch and the A-pillar and sill frame). It provides effective acoustic insulation of the cabin from tire rolling noise and airflow, prevents mud and leaves from accumulating in the closed profiles of the door opening, and protects the bodywork structure from corrosion caused by trapped dirt.

Fitment guarantee and VIN verification

Each cover undergoes a detailed material structure inspection, mounting point check and cleaning before shipping.

Fitment / installation note: The initial designation 4K8 (body group 821) indicates the geometry designed specifically for the fender profile and A-pillar area of the Audi A7 Sportback. Correct installation of this cover is essential to maintain the factory acoustic insulation of the cabin and protect the internal door openings from water and dirt entering from under the wheel. Before purchasing, we recommend comparing the OE number on the part label/embossing or verifying it using the vehicle's VIN.
