The supply on M20 alternators for the E30 M3 & 325 models (and E28 528e) has been difficult in recent years. Truly good rebuilt alternators are few and far between, and generally only good if done through an OE level manufacturer with super high quality and testing standards. Normally our "go to" on this application is a Bosch rebuilt unit, but they are often not available when needed.  

This is an authentic Genuine BMW alternator, 90 amp version, for the E30 325 models (325, 325i, 325is, 325ic, 325e, 325es, 325ix) and E28 528e. Many of these cars came with an 80 amp alternator, so for this cars this is technically a bit of an upgrade with a modest increase in electrical power output. 

This is what's considered a “Factory reman” or factory refurbished unit, and is the same you would find at a BMW dealer – if they actually stocked them! BMW's own supply of this alternator has gotten quite low, and with that the price on these keeps creeping up and up. But if you need a top quality factory alternator, or are doing a concours level restoration where only Genuine BMW parts are desired, this is the real deal authentic BMW solutions. It is BMW part number 12312287828 (12 31 2 287 828). 

This alternator is often sold under the Bosch part # AL46X, but this is the Genuine BMW which goes through different remanufacturing and testing channels. This alternator is also sometimes sold under other / older BMW part numbers including: 12311288409 (12 31 1 288 409), 12311726603 (12 31 1 726 603), or 12311466086 (12 31 1 466 086).
