• Electrical system instability under load

Installation Notes

Verify pulley style, plug clock position, rotation direction, and amperage rating before installation. This alternator uses a serpentine belt pulley setup with a clutch pulley and a 12 o’clock connector position, so matching the original unit is important for proper fitment on BMW charging systems. Confirm the vehicle’s OE alternator specification against the part number 11300 before replacement.
