Coolant Pipe / Aluminum Cooling System Mainline – 06M121481AA

Original rigid cooling system pipe (metal coolant circulation line for the engine block / thermal management system water main), designed for Audi A7 Sportback (4K / 4K8 generation) and Audi A6 C8 (4K2 / 4K5 / 4KA type) with 3.0 V6 TFSI (55 TFSI designation / EA839 family / DLZA, DKMB, and related codes) turbocharged petrol engines based on the modular MLBevo longitudinal platform.

Original VAG cooling system component. Made from precision-cast and formed aluminum alloy with high thermal conductivity, featuring factory-spec face flanges for O-ring seals and integrated mounting ears for engine block mounting bolts. It is resistant to the extreme temperatures inside the cylinder bank ("hot-V"), high operating pressures, and prolonged contact with engine coolant (G12evo / G13). It ensures rigid fluid transfer in critical areas of the powertrain cooling system, eliminating the risk of deformation, cracking, and leaks.

Fitment guarantee and VIN verification

Each pipe undergoes verification of face flange geometry, unobstructedness, and a pressure leak test before shipping.

Fitment / installation note: The 06M prefix assigns the component directly to VAG V6 petrol engine accessories (EA839). The precise bend angle and factory mounting ear spacing in the OEM version ensure a completely interference-free fit of the mainline against the engine block. It is recommended to install new O-ring seals before installation. Before purchase, we recommend comparing the full OE number with the suffix (AA ) marked on the pipe body or verifying it using the vehicle's VIN.
