When This Colorado and Canyon Ignition Kit 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. Similar symptoms can also come from wiring, connectors, injector faults, fuel delivery problems, vacuum leaks, or compression issues. For service sequence planning, review the Colorado Canyon ignition service workflow.

UF303 and 5019 Reference Checks

Compare 5073, 49174, 48844, UF303, UF-303, 1788390, 12568062, 12570616, 8125680620, and 8193009210 with the original coil.
Also compare 71760623, 19300921, 6737200, GN10114, SPP44, SKIC079, 5C1392, C1395, C642, COP44, C642M6, and V51700033 where applicable.
Compare spark plug reference 5019 with the plug specified for the engine.
Confirm connector orientation, coil body, mounting depth, plug reach, seat type, heat range reference, and gap requirement.

Installation and Service Notes

Install on a cool engine, inspect old plugs for fouling, check plug wells and connector locks, and follow vehicle-specific torque and gap guidance. If a misfire remains after installation, continue diagnosis by checking wiring, fuel pressure, injector operation, intake leaks, and compression. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded Chevrolet, GMC, or Isuzu part.

Q: Will this UF303 ignition coil and spark plug set fit my vehicle?
A: It is listed for Chevrolet Colorado and GMC Canyon 2004-2006 2.8L L4, Isuzu i-280 2006 2.8L L4, and Isuzu i-290 2007-2008 2.9L L4 applications.

Q: What is included in the package?
A: The package includes 4 ignition coils and 4 iridium spark plugs for the listed L4 service quantity.

Q: Which OE or interchange references should I compare?
A: Compare UF303, UF-303, 12568062, 12570616, GN10114, C642, COP44, and spark plug reference 5019 with your original parts.

Q: What symptoms may point to worn ignition coils or spark plugs?
A: Common symptoms may include rough idle, hard start, hesitation, misfire symptoms, poor acceleration, reduced 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 wiring, connectors, injector faults, fuel delivery, vacuum 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 Chevrolet, GMC, or Isuzu part.
