BMW Alternator / Generator (250 Amp) OEM 8611280 – a used genuine unit from a donor vehicle. This high-output alternator (also called a generator) charges the battery and powers the electrical system in 4.4L V8 turbocharged and mild-hybrid engines. A failing alternator can cause dimming headlights, a battery warning light, or a no-start condition. This 250-amp part was pulled from a BMW and is ready for install.
