This genuine OEM AC hose/line/pipe, part number 8W1816720G (also replaces 8W1816720), is a used component removed from an Audi. Found on models with 2.0L, 2.9L, and 3.0L engines, it carries refrigerant between the compressor, condenser, and evaporator. A failing AC line often leads to reduced cooling or a refrigerant leak, making this an essential part for restoring proper air conditioning function.
