Exhaust Valve for BYD Bao 5 & New e6, OE 12939676-00

This valve fits more than one model, which makes the fitment table on this page the only reliable check. Do not go by the model name in the title alone, because the same name can apply to builds with different engines. Match your car's exact variant and year in the table before you order. If your car is close to one of the entries but not clearly listed, send a photograph of the old part and its label through the quote route and we will confirm it against the OE number rather than leaving you to judge it by eye.

Small engine parts are frequently ordered against a supplier code instead of the OE marking. If the number you are working from came off paperwork rather than off the part, treat it as a starting point and check it here. A valve is too small to carry much marking of its own, so where you are unsure, give us the vehicle details through the quote route and we will confirm the reference before you order.

Delivery takes 8 to 25 days from your order to your door. If the head is coming off, order before the strip down and not after it, so the engine is not standing open while you wait. Quote the OE number when you order and again if you ask us for an update, because that is what we can look the line up against.

This valve is made from metal, and nothing more specific than that is given. Take it as confirmation of what you are buying rather than as a specification to work from. If your engine build needs a particular grade or a particular seat treatment, that has to come from the vehicle manufacturer's documentation and not from this page. We do not publish clearances or fitting figures for it. Handle the valve carefully in transit and keep it in its packing until the machining work is ready for it.

The mounting position for this valve is the engine bay, which for a valve means it sits inside the cylinder head and not anywhere you can reach with the bonnet up. Fitting it is engine work rather than a roadside swap, and it usually happens with the head already off and on a bench. Bear that in mind when you plan the order, because the surrounding gaskets and any machining are decided by what the engine looks like when it is apart, and none of that is described on this page.

A single version of this valve is offered. The Original/Genuine listing carries the BYD name and no Aftermarket line has been catalogued for OE number 12939676-00, so there is one tier on this page instead of two. Valves are usually replaced together during head work, so if you need several, order them against the same OE number and avoid mixing references. If you want the fitment on your engine confirmed first, use the quote route with a photograph of the old part and its label and we will confirm it against the OE number.
