Storage & logistics

Exchange standard turbos for the 4.2 TDI 326 hp must be stored in a climate-controlled environment to prevent moisture damage to the core and internal components. For wholesale buyers, palletized storage with desiccant packs ensures the turbos remain in optimal condition until delivery. Garages should inspect packaging for damage upon receipt and store units in a dry, temperature-stable area to maintain performance characteristics. Regular inventory rotation is recommended to avoid stock obsolescence, especially for turbos with limited shelf life due to core condition.
