BMW OE number, as listed in aftermarket supplier catalogues. Compare listings for this exact number, then confirm the part number and vehicle fitment before ordering.
Supplier articles whose catalogue lists 21 21 1 207 321. Check the supplier’s own restrictions before ordering. A fitment condition under a part number is one its supplier names for at least one of the vehicles the part is listed for, not for all of them: a vehicle’s page shows which apply to it.
What these parts’ suppliers state
Each value belongs to the part number beside it, not to the OE number: parts that list one OE number can differ. Where your vehicle manufacturer gives a value, it takes precedence.

Engine code and production dates decide fitment. Model name and year alone don’t.
