Is this alternator new or remanufactured?

It is 100% remanufactured by Bosch, not new. Bosch rebuilds and tests it to original-equipment performance, which is why it costs less than a new unit.

Will it fit my Mercedes-Benz?

It is listed for Mercedes-Benz cars, but fit depends on the model, engine and year. Check your car's original alternator part number and amperage against the AL0861X before ordering.

Does it come with the pulley?

Yes. The 6-groove serpentine pulley (51 mm outside diameter) and internal fan are included, so it bolts on without swapping parts from the old unit.

Is 220 amps enough for my car?

220 A is a high output meant for cars with heavy electrical loads. Match it to the amperage of the alternator you are replacing; a lower-output car does not need it.

One alternator assembly with the internal fan and serpentine pulley fitted. Mounting bolts and a voltage regulator are not listed as included.

How does it compare with a new OEM alternator?

It is built to be identical in fit and performance to the original equipment part, at lower cost. The trade-off is that it is remanufactured rather than new.
