This Audi auxiliary radiator air guide / duct (outer, left side) is a used genuine OEM part with part number 4G0121333G. Also called an air duct or radiator air guide, it channels airflow to the auxiliary radiator to support engine cooling. Designed for 3.0L V6 diesel and gasoline supercharged, and 4.0L V8 turbocharged engines in the A6 Quattro and S6, this duct helps maintain proper thermal management. Cracks or damage can reduce airflow and cause elevated coolant temperatures.
