Storage & logistics
For garages and wholesalers, proper storage of exchange standard turbos is essential to maintain their condition until installation. Keep units in a dry, temperature-controlled environment away from direct sunlight and contaminants. Store turbos in their original packaging or sealed containers to prevent moisture ingress or dust accumulation. Rotate stock regularly to ensure older units are used first, adhering to the first-in-first-out principle. Label each turbo with its reference, model compatibility, and inspection date to streamline inventory management and reduce the risk of mismatched installations.
