Installation Notes

Verify the vehicle’s original starter rotation, tooth count, mounting style, and electrical specification before installation. This unit is a clockwise-rotation, flange-mount starter with a 9-tooth pinion, so matching the original unit is important for proper engagement. Confirm fitment by year, model, and production notes for BMW applications such as 2004-2005 BMW 525i, 2003 BMW Z4, and 1996-2002 BMW Z3.

Quality Assurance

WAI manufactures this starter as a brand-new unit rather than a remanufactured assembly. The design and proprietary production process are used to support maximum life and dependable starting performance across the listed BMW fitments.
