3-Gallon Aluminum Air Tank

The TGK Motorsport Air Tank Upgrade is engineered to replace the undersized factory air tank in C7 Audi A6/S6/RS6/A7/S7/RS7 models, significantly improving air suspension performance. This 3-gallon seamless aluminum tank provides sufficient stored air capacity to raise the vehicle from a lowered state to ride height without engaging the factory compressor, reducing strain and wear on the system. The tank includes a machined mount for secure attachment to the battery tie-down, facilitating an easy integration into the existing setup. The tank features five 1/4" ports, offering versatility for future modifications like the addition of an aftermarket external compressor or additional airlines. This air tank upgrade is compatible with aftermarket air suspension kits. It specifically addresses fitment challenges in vehicles equipped with factory Bang & Olufsen sound systems or models like the A7/S7/RS7, where the factory subwoofer placement often prevents other aftermarket tanks from fitting in the spare tire location. The TGK tank is designed with a slim profile to fit alongside the factory subwoofer without requiring its removal. Please note that installation of this air tank upgrade means that a spare tire can no longer be accommodated in the vehicle.
