Genuine BMW Alternators

Genuine BMW Alternators:  Small, lightweight and powerful: a Genuine Original BMW Alternator is a true service provider. Able to withstand vibrations with an acceleration of up to 80 times that of gravity, stable up to a voltage of 350 volts, it offers a particularly long service life thanks to its sophisticated design. Every Original BMW Generator is tailored precisely to the specific characteristics your BMW and due to its tough construction - is the ideal exchangeable part - with the same quality and performance features of a new component.  Shop our full line of Genuine OEM BMW Alternators for most BMW models and years!  With our huge BMW parts inventory, you can count on low pricing, fast order processing, and lightning quick shipping of Genuine BMW alternators!

Genuine BMW Remanufactured Parts:  The underlying idea behind a remanufactured part is recycling: up to 60% of parts can be re-utilized at the end of their specified lifetime. Yet every exchangeable part is subject to exactly the same quality specifications as a Genuine Original BMW Part and it even carries the same 24-month/unlimited warranty. 95% of all parts that cannot be directly refurbished are recycled, and these figures make sense: not only for the environment but for your pocket as well – BMW Remanufactured Parts cost up to 50% less than the new component.
