Piston for Audi A4: Titanium Alloy
This piston for the Audi A4 is specified around titanium alloy, 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 packing that arrived crushed at the port, or a specification nobody had written down. Both are specification problems, and both are preventable.

Fitment notes
Check whether the mounting points on your market version match the catalogue drawing — regional variants are the usual cause of a wrong first order.

The specification above is the one most often ordered for coastal delivery. Related applications include mining sites, rural transport, motocross, farm use, ride-hailing fleets.
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 E-mark-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
What testing is included?
Standard lots ship with dimensional and hardness reports. E-mark documentation is issued with the shipment when your market requires it.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
