Fitment & Installation Checks

Match year, model and exact 1.3L hybrid engine.
Compare connector keying, coil body, mounting point, boot profile and printed reference numbers.
Confirm spark plug reference 5325 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 UF374 and 5325 kit fit my Honda Civic?
A: It is listed for 2003-2011 Honda Civic Hybrid 1.3L applications; confirm the exact hybrid engine and references before ordering.

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

Q: Why does a 1.3L four-cylinder Civic use 8 coils and 8 spark plugs?
A: This listed Civic Hybrid ignition arrangement uses two ignition positions per cylinder. Confirm the exact hybrid engine before ordering.

Q: Which ignition coil references should I compare?
A: Compare UF374, C1408, 5C1405, E404, 52-1755, IC504, 30521-PWA-003 or 30521-PWA-S01 where applicable.

Q: Which spark plug reference is included?
A: The listed spark plug reference is 5325.

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

Q: Should all eight coils and plugs be replaced together?
A: That depends on diagnosis, condition, mileage and maintenance history. Confirm the service plan before replacing a full set.

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

Q: What should I compare on the original coil?
A: Compare connector keying, coil body, mounting point, boot profile and printed part number.

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 replacement?
A: Continue diagnosis of wiring, injectors, fuel delivery, air leaks, sensors, compression and mechanical timing as applicable.
