Vehicle fitment

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

154 vehicles in 12 model series, inferred

Aftermarket parts that list 21521157212 fit these vehicles according to their supplier catalogues. That does not prove 21521157212 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
