Product matching notes

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

How do I confirm CF-20446N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around BMW - Europe 1 (E81) Eng.N43 B16 A 116 i 89kw, BMW - Europe 1 (E81) Eng.N43 B16 A, N45 B16 A 116 i 90kw, BMW - Europe 1 (E81) Eng.N43 B20 A 118 i 105kw and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 180A, Pulley Class: SC7, Regulator/Fan: IR/IF, then cross-check OE numbers BMW 12-31-7-542-351, 12-31-7-550-469, 12-31-7-582-699, Bosch 0 121 715 017.

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 20446. That usually narrows the match quickly.
