Storage & logistics
For workshops and private users, storing OM651 injectors requires protection from moisture, extreme temperatures, and physical shocks to maintain their integrity. Exchange-standard units should be kept in sealed packaging until installation, while remanufactured injectors benefit from climate-controlled environments to prevent seal degradation. Bulk purchases should be organized by reference and motorization to streamline inventory management and reduce handling errors. Always inspect injectors for damage or contamination before installation, as even minor defects can compromise engine performance.
