Technical specifications — Thickness [mm]: Steel, Carbon mm, Diameter [mm]: 85 mm, Length [mm]: 388 mm, Width [mm]: 162 mm — are verified against the OEM data sheet to guarantee fitment accuracy and performance parity with the original equipment. Compatible with BMW vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 00.154.44, 08.10.005, 10069100, 11121715452 and 45 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
