O.E.M.

When a part is labeled as O.E.M., it means it comes from a manufacturer that originally supplied the automaker. In the case of vehicles that are 30 to 40 years old, it’s common for small German manufacturers to still produce these parts — supplying both local distributors and the automaker's own network. This is typical for many low-volume parts from older vehicles. Since this item is distributed through a German supply network, it may arrive in unbranded packaging, but the quality matches what you'd receive directly from the dealer.
