Alternator, Rebuilt, Bosch - E30 325e/325i/M3, E28 528e

Has your E30 alternator suffered a failure? This OEM-remanufactured Bosch alternator is a direct replacement solution for 1986+ E30 325e/325i, E30 M3, and E28 528e BMWs which came with BMW part number 12312287828, 12311288409, or 12311726603 and costs many hundreds LESS than what you'll pay for the same alternator at the BMW dealer.

This alternator is a Bosch AL46X, rated at 90 amps. If your BMW came with a slightly smaller amperage generator (such as a 80 amp) than this alternator is actually a slight upgrade, and will be able to handle a higher electrical draw (great for those who use lots of electrical accessories, or have upgraded their stereo or lighting).

A $40 core charge applies to this sale which will be added during order processing. The core charge may be refunded once an original Bosch alternator is returned.
