Right Floor Air Duct / Passenger Footwell Air Supply Duct – 4K8819502

Original right floor air duct (lower air distribution duct / passenger-side footwell and floor area air duct), 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-tier S/RS models based on the modular MLBevo longitudinal platform.

Original VAG factory component of the internal heating and ventilation (HVAC) system. Made of lightweight, durable thermoplastic material resistant to mechanical deformation and high temperatures of the supplied air. Mounted under the floor carpeting and the right-side interior console. It is responsible for precisely delivering a stream of warm or cool air from the heater unit directly into the passenger footwell area (and towards the rear row of seats), ensuring proper thermal balance in the cabin, system tightness without pressure loss, and quiet ventilation operation.

Fitment guarantee and VIN verification

Each duct undergoes a detailed flow test, inspection of the mounting flanges, and cleaning before shipping.

Fitment / installation note: The initial designation 4K8 (group 819) indicates the floor duct geometry profiled for the specific floor panel and sill indentations of the Audi A7 Sportback model. Proper installation under the carpeting prevents the duct from kinking under foot pressure and eliminates heat loss in the footwell area. Before purchase, we recommend comparing the OE number stamped on the part body or verifying fitment using the vehicle's VIN.
