Fitment & Installation Checks

Match year, make, model and exact 5.6L V8 engine.
Compare connector keying, coil body, mounting point, boot profile and printed reference numbers.
Confirm spark plug reference 4505 for the exact engine.
Follow the vehicle manufacturer's spark plug gap and torque specification; do not guess.
Inspect wiring, connectors and plug wells for damage, oil or moisture before installation.

Diagnostic note: A DTC or misfire code alone does not prove an ignition coil is faulty. If a misfire remains, continue diagnosis of wiring, injectors, fuel delivery, intake or vacuum leaks, sensors, compression and mechanical timing as applicable.

Q: Will the UF551 and 4505 kit fit my Nissan or Infiniti?
A: Confirm the listed year, exact 5.6L V8 engine, connector and reference numbers before ordering.

Q: What is included in this kit?
A: The package includes 8 ignition coils and 8 spark plugs.

Q: Does the 8 + 8 package match the listed V8 applications?
A: The package contains eight coils and eight spark plugs; verify the exact engine and service requirements before installation.

Q: Which ignition coil references should I compare?
A: Compare UF551 and the listed references including 22448-ZE00C, 22448-ZE00A, GN10247 and C1672 where applicable.

Q: Which spark plug reference is included?
A: The listed spark plug reference is 4505.

Q: Does a misfire code prove the ignition coil is bad?
A: No. Wiring, injectors, fuel delivery, air leaks, sensors, compression or mechanical problems can also cause misfires.

Q: Should all coils and plugs be replaced together?
A: Use diagnosis, age, mileage and component condition to decide whether full-set service is appropriate.

Q: Do I need to verify spark plug gap and torque?
A: Yes. Follow the exact vehicle and engine service specification.

Q: What should I compare before ordering?
A: Compare year, engine, connector keying, coil body, mounting point, boot profile and printed references.

Q: What should be checked during installation?
A: Inspect connectors, wiring and plug wells for damage, oil or moisture and make sure each coil is fully seated.

Q: What if the engine still misfires after installation?
A: Continue diagnosis of wiring, injectors, fuel delivery, intake leaks, sensors, compression and mechanical timing as applicable.
