Aftermarket part numbers

Supplier articles whose catalogue lists 1 733 803. 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.

Vehicle fitment

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

248 vehicles in 60 model series, inferred

Aftermarket parts that list 1 733 803 fit these vehicles according to their supplier catalogues. That does not prove 1 733 803 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
