How can I verify that 25860-31120 is a genuine Toyota part?
A genuine Vacuum Switch Valve shows the Toyota number 25860-31120 on the box label with the country-of-origin marking. On the part itself, the metal carries the supplier’s mark cast or stamped next to Toyota’s own mark, not a separate printed sticker; and the part number is die-stamped or laser-etched into the metal itself rather than printed in ink, and it matches the box label. Documentation is available on request – commercial invoice, packing list and Certificate of Origin.

How many pieces are needed for 25860-31120?
You get one piece per position – check the quantity required for your application.
Is the genuine part worth it compared with an aftermarket equivalent?
The genuine part differs in ways that show up in service: the OE heat treatment and surface finish help the part resist wear, corrosion and seizing, and the part is machined to OE tolerance, so it mounts and seats without shimming or rework.
What documentation comes with an order?
Commercial invoice and packing list accompany every shipment, and a Certificate of Origin can be issued on request; the part number is die-stamped or laser-etched into the metal, so you can match it against the invoice.
