Spark Plug for BYD Tang DM-i & Tang DM-p, OE 12633651-00

This reference fits a wide spread of vehicles, which is helpful but also a reason to be careful. Go by the fitment table on this page rather than by the name Tang DM-i or Tang DM-p on its own, since variants within a model line do not always share the same ignition parts. If you still have a plug out of the engine, read the number on it and compare. When the table and your car do not line up cleanly, check the model and model year on your registration document and send that through the quote route so we can check before you buy.

Both are printed on this page so that a buyer holding either one can find their way to the correct listing. If what you have matches neither, do not assume from appearance that a plug is a plug. Read the marking carefully, note your Tang variant, and send the two together through the quote route on this page. We will match it against the fitment table and tell you what the right listing is.

Allow 8 to 25 days for delivery, counted from your order to your door. If you are ordering a set for one car, order the whole quantity in one go rather than in separate orders placed days apart. Where a service is already booked, tell us the date through the quote route on this page before ordering, and we will say whether the timing works.

It is made of metal. The electrode material and heat range are not stated for it, so match them against the plug you are replacing rather than assuming. Metal parts still want careful handling, so leave it boxed until the engine bay work begins. If your workshop needs a full material specification in advance, ask for it through the quote route on this page.

The mounting position for it is the engine bay, and it is catalogued under ignition. No side and no front or rear position applies to it, so nothing about this item is handed and the engine bay is as precise as it gets. That is enough to tell you the work happens under the bonnet rather than anywhere else on the car. For anything more exact about your own Tang DM-i or Tang DM-p, work from the fitment table on this page before ordering.

Only one has been sourced against this reference. BYD is the genuine manufacturer, and there is no Aftermarket entry for OE 12633651-00, so the Original/Genuine tier is all that appears on the page. What you see listed is what has actually been sourced, rather than what might exist somewhere in the market. Where two tiers do exist for a part, both are shown openly on the page. If you would like us to look for another supply here, put the request through the quote route with your Tang details and we will come back to you either way.
