Passenger Footwell Air Duct for BYD Seal 06 DM-i, OE 12318909-00

This one is the right-hand part, described on the page as the passenger-side footwell air duct. Sides are given as you sit in the driver's seat looking forward, so the description does not change with which side the steering wheel is on. The matching left-hand duct is a separate item and will not seat where this one goes. Before ordering, look at which side of the cabin your old duct runs down into the footwell, then check that against the fitment table on this page for your BYD Seal 06 DM-i.

This duct is listed under OE 12318909-00 and also carries the alternative reference HAD-8100132. Printed labels and supplier paperwork do not always use the same number, so a reference that does not match the title is not by itself a sign of the wrong part. Wipe the old duct clean and read whatever is moulded or printed into it, then compare it with both numbers. If it matches neither, send what you can read through the quote route on this page and we will check it against the fitment table.

Allow 8 to 28 days for delivery, counted from your order to your door. Plan from the later end of that range if a workshop slot depends on the part being in your hands. Nothing here is a fixed calendar date from a courier, so book labour once the duct has actually arrived. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.

It is a plastic part. That mostly affects handling. A moulded duct locates on its own seating faces, so it should go into place by hand rather than being forced into an opening it does not match. Keep it flat and unloaded until fitting day so nothing presses a flat spot into the moulding.

Only the Original/Genuine version of this duct is listed, made by BYD. Where an Aftermarket equivalent exists for a part, we show both tiers on the same page and let you pick. For this OE number there is no second listing, so the genuine duct is the one version offered. That reflects what we can source against 12318909-00 rather than any view on the part itself. If you would like us to look for an alternative reference, use the quote route on this page and give the OE number, or send a photograph of the old part and its label.
