993 parts sourcing audit

Read the individual part guides: specifications, buying sources and fitment notes →

One exact factory reference at a time: a direct Genuine Porsche purchase page, a direct alternative-manufacturer or performance page, and the original-equipment maker's own reference when the evidence supports it. Search pages and guessed fitment do not count.

Distinct 993 references: 6,013
Complete: 993
Remaining: 5,020
Coverage: 16.51%
Technical profiles: 70
Technical fields sourced: 145
Technical profiles pending: 923

What “complete” means here. The factory reference was found in the 993 PET, and both buying pages name the exact application or reference. Review dates belong to each source, not to the whole catalogue. Dataset last updated on 8 September 2026. Stock and prices can still change. A page that refuses automated clients is labelled as such; it is not silently marked dead or reachable.

Weight, dimensions and material are audited separately. A purchase pair can be complete while its physical data remains pending. Each published value names the exact Genuine, OE-supplier or alternative reference it describes and links to its own source. A shipping weight, package size or value inferred from a photograph is never substituted for a part specification.

Research queue. 2,107 references have at least one exact catalogue-product lead to investigate; 3,700 still have no local product lead. Leads are excluded from the complete count until both current buying pages and the non-Porsche manufacturer identity have been checked.

Evidence rules

Exact Porsche reference on every purchase page; no search-result URLs, inferred fitment or generic category pages. Original-equipment manufacturer references require an explicit cross-reference or OEM claim from a manufacturer or the named product seller.

“Genuine Porsche”, “original-equipment supplier” and “aftermarket” are separate claims. A Bosch cross-reference, for example, does not prove that every Bosch-branded replacement is identical to the Porsche-boxed part; the recorded evidence says exactly what was verified.
