Important Notes

Important — fitted with clutch style pulley (OAP). Confirm clutch pulley type matches original; clutch pulleys absorb belt-tensioner shocks and cannot be swapped for solid pulleys without proper engineering assessment.

Recommended to confirm by OE number due to different regulator functions across BMW N54/N55/N57 variants. Several internal regulator configurations exist — incorrect selection may cause warning lamp or charging issues.

High-output unit suits BMW twin-turbo six-cylinder petrol (N54/N55) and diesel (N57) applications including 1 Series, 3 Series, 5 Series, 6 Series, X5, X6, and Z4 platforms.
