5710869 Ignition Coil for Cummins X12 X12N 12L Natural Gas Engine | RJT PARTS
Product Overview
The 5710869 ignition coil delivers high-voltage spark to the cylinders in Cummins 12-liter natural gas engines. Foton Cummins builds this coil for the X12 and X12N platforms — engines that power heavy-duty trucks across China and export markets. It converts 12V battery current into the thousands of volts needed to fire the spark plugs cleanly under load.
RJT PARTS supplies the 5710869 coil as a direct-fit aftermarket replacement. It matches the original Cummins mounting points and electrical connector, so your technician installs it without modification. Every unit passes bench testing for insulation resistance and spark output before we pack it for shipment.
The X12N engine produces 400 to 460 horsepower and meets China VI (National 6b) emission standards. Therefore, it runs at high combustion pressures and demands reliable ignition performance. Our 5710869 coil meets that demand at a lower price than the dealer channel.
Cross-Reference OEM Numbers
| OEM Number | Status | Notes |
|---|---|---|
| 5710869 | Primary | Foton Cummins X12 / X12N factory number |
Note: 5710869 is a dedicated part number for the 12-liter X12 platform. It does not interchange with the 3964547 series (8.3L/8.9L engines) or the 5557908 series (15L engines). Always confirm your original part number before ordering. If you need help identifying the correct coil, send us your engine nameplate photo.
Compatible Cummins Engine Models
| Engine Series | Displacement | Power Range | Applications | Fuel | Coils per Engine |
|---|---|---|---|---|---|
| X12 | 12L | 380–430 HP | Heavy-duty trucks, tractors | CNG / LNG | 6 |
| X12N | 12L | 400–460 HP | National VI trucks, regional haul | CNG / LNG | 6 |
Diesel versions of the X12 do not use this part. This coil fits spark-ignited natural gas engines only. Diesel X12 engines rely on compression ignition and require no ignition coil.

Key Features
- 12L platform specific. Designed for the higher cylinder pressures of Cummins X12 and X12N gas engines.
- Heat-resistant construction. Epoxy-sealed housing withstands under-hood temperatures in long-haul truck applications.
- Direct fit. Matches OEM connector and mounting bolt pattern — no wiring changes.
- Consistent spark energy. Maintains stable voltage from idle through full-load highway cruising.
- Cost-effective. OEM-level performance at a lower aftermarket price point.
Failure Symptoms — When to Replace
- Engine misfire under load or at highway speed
- Check engine light with misfire codes (P0300–P0306)
- Increased fuel consumption or higher gas usage
- Rough idle or hesitation on acceleration
- Loss of power, especially on gradients
- Visible cracks, carbon tracking, or burn marks on the coil body
Fleet maintenance tip: On high-mileage X12N trucks, replace all six coils during a major tune-up. Mixed-age coils cause uneven combustion and shorten the life of the newer units. RJT PARTS offers discounted 6-coil engine sets.
Installation Notes
- Disconnect the negative battery cable before starting.
- Remove the engine cover and any intake piping blocking the coil pack.
- Unplug the electrical connector from the faulty 5710869 coil.
- Remove the hold-down bolt and pull the coil straight off the spark plug.
- Compare the old coil with the new unit to confirm matching dimensions and connector orientation.
- Apply dielectric grease to the inside of the new coil boot before installation.
- Seat the new coil and torque the mounting bolt to Cummins factory specification.
- Reconnect the harness and battery. Clear stored fault codes and start the engine to verify smooth operation.
Follow Cummins service manual lockout/tagout procedures for natural gas fuel systems before servicing.

FAQ
Q: What engine does the 5710869 ignition coil fit?
A: It fits Foton Cummins X12 and X12N 12-liter natural gas engines. These engines commonly power heavy-duty trucks and meet China VI emission standards.
Q: Can I use the 3964547 coil instead of 5710869?
A: No. The 3964547 fits 8.3L and 8.9L engines (CGE8.3, 6CT, ISL). The 5710869 fits the 12L X12 platform. They have different dimensions and electrical characteristics.
Q: How many coils does an X12N engine need?
A: The X12 and X12N are 6-cylinder engines, so they use 6 ignition coils — one per cylinder.
Q: Does this coil fit the diesel X12 engine?
A: No. The 5710869 fits the natural gas (CNG/LNG) version only. Diesel X12 engines use compression ignition and do not require ignition coils.
Q: What is the warranty?
A: 12 months from the date of delivery. We replace any coil that fails due to manufacturing defects.
Q: Do you ship to my country?
A: Yes. We ship worldwide, including Southeast Asia, the Middle East, Africa, South America, and Eastern Europe.
