- Part identity
- Ask for model-specific drawings, OE reference used only for identification, inlet and outlet diameter, body and overall length, and port alignment. Matching shell shape does not prove vehicle fitment.
- Supply condition
- Clarify new versus remanufactured supply, stainless or aluminized material, internal structure and whether hangers ship in the packing unit. Condition belongs to the named supplier line, not to this website.
- Order evidence
- Ask for sample approval identity, batch traceability marks, gross package weight and pieces per carton. Sample acceptance is not automatic approval of later lots.
- Quote boundaries
- Confirm validity, Incoterms, destination ZIP code, taxes, service scope and exclusions. Optional budget is a buyer planning input, not a published market discount.
