Aftermarket part numbers

Supplier articles whose catalogue lists 1 730 449. 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.

Vehicle fitment

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

126 vehicles in 18 model series, inferred
