Direct answer: Yes, as a checking service rather than a lookup. The buyer sends the factory part number together with the model and the model year, and Intiracing checks whether a corresponding part already exists in the catalogue or whether a new tool would have to be built.
The model and year are not optional, because a factory number alone does not describe a position. Two hulls can carry the same engine and a different exhaust section, and the same position can change between years. With the number and the year, the check runs against the catalogue wording for that position, and the answer is either an Intiracing number or a note that none covers it.
Where nothing matches, the drawing or sample route applies: evaluation, quotation, sample with the tooling fee, approval, deposit, then production. An Intiracing number is not derived from a factory number and does not replace it on a parts list. It identifies an Intiracing part, and the fitment line on the listing remains the confirmation.
