Alternator for BMW 3 Series: Reinforced Nylon
This alternator for the BMW 3 Series is specified around reinforced nylon, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is a fitment that looked right on paper and failed on the bench, or packing that arrived crushed at the port. Both are specification problems, and both are preventable.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
Where it is used
The specification above is the one most often ordered for off-road trails. Related applications include airport ground fleets, coastal delivery, mining sites, heavy load hauling, long-distance touring.
Quality and packing
- In-line inspection with AQL 4.0 sampling on every lot.
- Dimensional report issued against the approved drawing.
- Carton marking and barcode to your specification.
- Golden sample retained at the factory as the reorder reference.
Questions buyers ask
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ECE R90-compliant build instead of a fresh interpretation.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
What testing is included?
Standard lots ship with dimensional and hardness reports. ECE R90 documentation is issued with the shipment when your market requires it.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
