Engine Performance Additive Specification Example for Workshop Replacements: All-Weather Version

This is a worked specification for engine performance additive in a all-weather version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The all-weather version version exists because the duty cycle on workshop replacements is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — PU Leather, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Questions buyers ask

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

What testing is included?

Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.

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.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
