Product Overview

The ignition coil, OEM number 12131712219, is fitted across an unusually wide range of BMW models powered by the M54 and S54 engine family, including the E46 3 Series (325i, 325Ci, 325xi, 330i, 330Ci, 330xi), E39 5 Series (525i, 530i), E38 7 Series, E53 X3 and X5, E36/E85 Z3 and Z4, and the M3. This part number has since been superseded by 12138616153, though 12131712219 remains widely referenced and stocked across the aftermarket. Since each vehicle uses six of these coils and the part spans so many BMW models, it's a genuinely high-turnover part for anyone stocking BMW ignition components.

Worn or failing units typically show up as an engine misfire, rough idle, sluggish acceleration, or a check engine light with a misfire code. GSK Auto manufactures this ignition coil to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this coil has been officially superseded by 12138616153, and since each vehicle uses six coils, it's worth confirming quantity needs with your customer before shipping.)

What Is an Ignition Coil?

Function: The ignition coil converts the vehicle's low battery voltage into the much higher voltage needed to create a spark at the spark plug, firing each cylinder at the precise moment required for combustion.

Working Principle: On this coil-on-plug design, one coil sits directly above each spark plug, receiving a low-voltage signal from the ECU and stepping it up to the high voltage required to jump the spark plug gap and ignite the air-fuel mixture in that cylinder.

Importance: Because each cylinder has its own dedicated coil on this engine family, a single failing coil causes a misfire specific to that cylinder, which can trigger a check engine light and, if left unaddressed, potentially damage the catalytic converter over time.

Common Failures & Signs: Internal winding breakdown from heat and age, often accelerated by fuel or oil residue contamination. Engine misfire, often felt as a rough idle or hesitation under acceleration. Sluggish acceleration or reduced power. Check engine light with a cylinder-specific misfire code.
