Which car brands share parts? A supplier-catalog cross-reference map

Several car brands have applications for the same supplier service part. That gives a rebuilder more ways to search and request quotes: the vehicle-brand reference, the supplier's order number and the other applications in the supplier's catalog. The useful evidence is an exact component entry, not a list of brands under common ownership.

Toyota and Subaru, BMW and Toyota, Mercedes-Benz and Renault, and Ford, Volvo and Peugeot all have concrete examples below. These are catalog-supported replacement opportunities. They do not establish that every genuine part in each pair is identical or that every engine version uses the listed item.

What does a shared supplier reference establish?

It establishes what that supplier catalogs for the applications shown. A supplier can offer one replacement for several vehicle-brand references without establishing that the original factory parts were the same component, made by that supplier or identical in every detail.

Keep two questions separate: “Does this supplier offer the same service product for both applications?” and “Can I buy the other brand's genuine part and fit it to my car?” The first answer can be documented in the supplier catalog. The second needs its own vehicle-specific evidence and current service-part check.

The map is a starting list of search routes. No donor vehicle, physical fit or installation has been tested by DNF.

Which cross-brand examples have exact catalog evidence?

The following compilation was checked on October 24, 2026. References in the fourth column appear in each supplier page's OE-number list. That list is separate from the vehicle application rows; it is not an instruction to assign every reference to every vehicle on the page.

Sources: C 2620, HU 6014/1 z, W 7032 and HU 711/51 x. Open end dates are reproduced as a catalog limitation; they do not establish coverage of every later generation or a vehicle built today. Production months are not a statement of North American model-year coverage.

How should you use the Toyota and BMW examples?

Search the exact reference for the application you have, then compare the alternative supplier route. Retain the entire number, including /1 z in the BMW/Toyota example and -00 in the Toyota air-filter reference.

Do not enlarge the example because another car shares a familiar engine name. The retained Supra row is for a 2.0 application; it is not evidence for every Supra 3.0. The BRZ/GT86 row is not a parts list for a GR86 or a later 2.4 BRZ. Likewise, finding Toyota in two different rows does not connect the two filter products.

This is how the map can save search time: it supplies a precise supplier number and a place to check the scope. It does not supply a price, an installed-cost result or a reason to skip the recipient-vehicle check.

Why do qualifiers matter on older European diesel projects?

The Mercedes/Renault example includes an equipment qualification for the selected Renault application. The Ford/Volvo/Peugeot example identifies selected engine variants and production periods. Those details belong in a supplier inquiry even when a broad marketplace listing says the filter suits the model.

Do not infer that all parts from those engines cross-reference. A shared service filter tells you nothing by itself about a control module, turbocharger, mounting bracket or complete engine assembly. Check each proposed component independently.

The catalog pages used here are global English entries. Confirm the market and VIN with the parts provider before treating a production range as applicable to a Canadian or US vehicle, including an imported project.

What should you ask when requesting the alternative quote?

Give the provider your VIN privately, the vehicle-brand number supplied for that VIN, the exact supplier service number, and the catalog application you found. Ask them to identify any supersession, equipment qualification, required seals, package quantity or other unresolved condition.

MANN+HUMMEL describes product-name, VIN and cross-reference searches in its online catalog. Use the current entry rather than an undated screenshot, and retain the source and lookup date with the quote.

Then compare the same scope: required quantity, new or used condition, included items, delivery, tax, returns and any installation work. A supplier-catalog match creates an option to price. It does not establish that the alternative is available or cheaper.

Where should the research stop?

Stop when the important qualifier is unresolved. Do not turn a shared engine, corporate relationship, similar housing or search-result headline into a part-number match. Use your repairer's current manufacturer information for the proposed work, especially where a part affects structural repairs, restraints, driver-assistance systems or high-voltage equipment.

Keep this map beside the evidence for a project when browsing damaged vehicles. Its role is to reveal a traceable sourcing question early, while you can still obtain the current part and installation information needed for the purchase decision.
