Product matching notes

Use these checks together with the application table before final ordering.

How do I confirm CF-13971N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around BMW - Europe 3 (E46) Eng.M52 B25 (256S4) 323 i 125kw, BMW - Europe 3 (E46) Eng.M52 B28 (286S2) 328 i 142kw, BMW - Europe 3 (E46) Eng.M54 B22 (226S1) 320 i 125kw and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 90A, Rotation: CW, Pulley Class: S6, then cross-check OE numbers BMW 12-31-7-501-592, 12-31-7-501-687, 12411432977, 12411740624.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 13971. That usually narrows the match quickly.
