When This D555 Coil and Plug Set May Be Needed

Ignition coils and spark plugs may need service when the engine has rough idle, hard start, hesitation, misfire symptoms, poor acceleration, reduced fuel economy, or a check engine light. Coil circuit faults can also involve wiring, module issues, connectors, or control signals. If related codes appear, review GM V6 coil circuit checks before replacing parts.

D555 and 3951 Reference Checks

Compare 10467067, 89056799, 19353734, 10472401, E530C, D555, CDR39, C503, and GN10123 with the original coil.
Compare 3951, TR55, 3186, TR5GP, 41-162, 19417055, 41-962, and 19299585 with the required spark plug.
Confirm that 3 ignition coils and 6 spark plugs match the service quantity for the listed 3.8L V6 application.
Check coil tower style, plug wire condition if equipped, plug reach, seat type, heat range reference, and gap requirement.

Installation and Service Notes

Inspect old plugs for fouling, check plug wires and coil towers, and follow vehicle-specific torque and gap guidance. If misfire symptoms remain, continue diagnosis by checking wiring, fuel pressure, intake leaks, compression, and ignition module operation. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded GM, Buick, Chevrolet, Oldsmobile, or Pontiac part.

Q: Will this D555 ignition coil and spark plug set fit my vehicle?
A: It is listed for selected Buick, Chevrolet, Oldsmobile, and Pontiac 3.8L V6 applications. Confirm exact year, engine, coil tower style, and plug reference before ordering.

Q: What is included in the package?
A: The package includes 3 ignition coils and 6 iridium spark plugs for listed 3.8L V6 service applications.

Q: Which OE or interchange references should I compare?
A: Compare 10467067, 89056799, 19353734, 10472401, D555, C503, GN10123, and spark plug references 3951 / TR55 with your original parts.

Q: What symptoms may point to worn ignition coils or spark plugs?
A: Common symptoms may include engine misfire, rough idle, hard start, hesitation, poor acceleration, poor fuel economy, check engine light. These symptoms should be diagnosed before replacing parts.

Q: Can this kit solve an engine misfire?
A: It may help only when the ignition coils or spark plugs are confirmed as the failed parts. Misfires can also be caused by wiring, fuel, air, sensor, or compression issues.

Q: Do I need to check spark plug gap and torque?
A: Yes. Always follow vehicle-specific service information for spark plug gap and torque. Do not force a plug into the cylinder head.

Q: Should I compare the connector and mounting style?
A: Yes. The connector shape, coil body, boot length, and mounting points should match the removed parts before installation.

Q: Should all coils and plugs be replaced at the same time?
A: That depends on the repair plan and diagnosis. Some owners service a full bank or full engine set, while others replace only the confirmed failed parts.

Q: What else can cause the same symptoms?
A: Symptoms may also come from plug wires, ignition module issues, wiring, fuel delivery, intake leaks, or compression problems. Check related systems if symptoms remain after installation.

Q: Is this a factory-branded part?
A: No. This is a BDFHYK OE-style aftermarket replacement, not a factory-branded GM part.
