Storage & logistics

For workshops and garages, proper storage of exchange standard injectors is essential to maintain their condition until installation. Keep injectors in their original packaging or a sealed container to prevent contamination from dust or moisture. Store them in a climate-controlled environment, away from direct sunlight and extreme temperatures, which can degrade seals and internal components. Label each injector with its OEM reference and batch number for easy identification during busy repair schedules. Regularly rotate stock to ensure older injectors are used first, reducing the risk of obsolescence. For motorists storing a spare injector at home, a dry, cool place like a garage or basement is ideal, but avoid areas prone to humidity or temperature fluctuations.
