Aftermarket part numbers

Supplier articles whose catalogue lists 1618 ER. 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.

14 vehicles in 9 model series, inferred

Aftermarket parts that list 1618 ER fit these vehicles according to their supplier catalogues. That does not prove 1618 ER itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
