Professional workshops should store remanufactured turbos in a climate-controlled environment, away from moisture and direct sunlight, to preserve their condition until installation. For bulk orders, use sturdy shelving and label each unit with its reference and model compatibility to prevent mix-ups. Always handle turbos with care, avoiding drops or impacts that could damage the CHRA or cartridge. For DIY users, store the turbo in its original packaging until ready for use, ensuring no contaminants enter the oil or air pathways during the replacement process.
