About This Part
Pencil-type ignition coil for BYD DM-i petrol engines, the coil-on-plug unit that fires the spark plug directly at the cylinder. Confirm OE 14257978-00 (also 472QC-3705100). The black moulded body carries an integrated connector and a long insulated boot that seats down the plug well. It covers a wide DM-i range including the Sealion 06 DM-i (2025-2026), Seal 06 DM-i Touring, Seal 06 DM-i and many more BYD models. Replace this ignition coil pack when you have a misfire, rough idle or a stored coil fault.

Frequently Asked Questions: OE 14257978-00
How do I know this coil fits my Sealion 06 DM-i?
Do not go by the model name alone. Find the OE number stamped on the coil you are removing and match it to 14257978-00, or the listed alternative 472QC-3705100, before you order. If the number on your old coil matches either of these, this is the right one. If you cannot find a clear number, take the coil out and check it against the fitment table on this page before buying.
The number on my old coil does not match 14257978-00, what now?
Do not fit it on a guess. Take the old coil out and read the number stamped or printed on its body before you order, since that is what confirms this is the right one for your car. If it does not match 14257978-00 or the alternative 472QC-3705100, hold off ordering and use the quote route on this page instead. Matching numbers on the physical part is the only reliable check, far more so than going by memory or by what the last coil looked like.
Where does the ignition coil sit on the Sealion 06 DM-i?
It sits in the engine bay, fitted directly to the ignition system rather than tucked away under trim. This one carries OE number 14257978-00 and is also listed as 472QC-3705100, made by BYD. If you are working from a part already off the car, matching that number against what you have removed is the surest way to know you are looking at the right component. Where you are not certain, the quote route on this page lets you send details through and get confirmation before you commit to an order.
