Storage & logistics

Storing remanufactured injectors for BMW 520i 170 hp engines requires careful handling to preserve their performance and longevity. Keep units in a climate-controlled environment, away from moisture and extreme temperatures, to prevent corrosion or seal degradation. For workshops, organize injectors by OEM reference and model year to streamline inventory management and reduce the risk of misplacement. Always store injectors in their original packaging or equivalent protective cases, ensuring the connectors and seals remain intact. Label each batch with the date of receipt and batch number for traceability, which is especially critical for warranty claims or quality audits. Avoid stacking heavy items on top of injector boxes, as this can compromise their structural integrity and lead to internal damage. Regularly inspect stored units for signs of wear or contamination, and rotate stock to prioritize older batches for use first, maintaining a fresh supply of high-performance injectors.
