Description

With a 140-amp output, this compact alternator is ideal for vehicles equipped with higher electrical draw accessories, such as upgraded stereo systems. It comes with a 2-year warranty and includes a refundable $70 core charge, provided the returned core matches the supplied part in fitment, type, application, accessories, and hardware, and is not damaged or modified. This alternator is compatible with a range of BMW E36 6-cylinder models including the M3 (1995-1999, 3.0 & 3.2 liter), 325i/325is (1992-1995), 328i/328is/323is (1996-1998), and the 1998-2000 MZ3 M Roadster/Coupe. It also fits the 1991-1992 E34 525i. If your vehicle originally came with an 80-amp alternator, this 140-amp model can be installed as an upgrade. A crucial installation note is the requirement for a 55mm alternator pulley. This alternator is supplied without a pulley, so you must reuse your existing pulley or acquire a compatible 55mm pulley separately if your original unit is not 55mm in diameter. Bosch, a major OEM producer for many automotive manufacturers, ensures high durability and reliability. This rebuilt alternator is backed by a Lifetime Replacement Program, offering worry-free ownership.
