This BDFHYK UF374 ignition coil and 5325 iridium spark plug set is designed for listed Honda Civic applications, including 1.3L L4 applications shown on this page. It is intended for ignition service when the original coils or spark plugs have been diagnosed as worn, weak, damaged, or related to misfire symptoms. Before ordering, confirm exact year, engine, UF374-style coil reference, 5325 plug reference, connector shape, and 4-coil / 4-plug quantity.

Fitment note: Honda Civic ignition parts can vary by year and engine. Do not order by Civic model name alone; compare the removed coil and plug references.

When This Honda Civic Coil and Plug Set May Be Needed

Ignition coils and spark plugs may need inspection when the engine has hard starting, rough idle, hesitation, misfire symptoms, reduced power, poor fuel economy, or a check engine light. These symptoms can also come from wiring, fuel delivery, intake leaks, sensor faults, or compression issues. For planning parts and labor, see Honda Civic ignition coil service planning.

UF374 and 5325 Reference Checks

Compare UF374, C1408, 5C1405, E404, 52-1755, IC504, 30521-PWA-003, and 30521-PWA-S01 with the original coil.
Compare spark plug reference 5325 with the plug specified for the engine.
Confirm that 4 ignition coils and 4 spark plugs match the listed L4 service quantity.
Check 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 connector locks, and follow Honda-specific torque and gap guidance. If symptoms remain after installation, continue diagnosis by checking wiring, fuel delivery, intake leaks, sensor data, and compression. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded Honda part.

Q: Will this UF374 ignition coil and spark plug set fit my vehicle?
A: It is listed for selected Honda Civic applications, including 2006-2011 Civic 1.3L L4. Confirm exact year, engine, coil reference, and 5325 plug reference before ordering.

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 UF374, C1408, 5C1405, E404, IC504, 30521-PWA-003, 30521-PWA-S01, and spark plug reference 5325 with your original parts.

Q: What symptoms may point to worn ignition coils or spark plugs?
A: Common symptoms may include hard start, rough idle, hesitation, misfire symptoms, reduced power, 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 wiring, fuel delivery, intake leaks, sensor faults, or compression issues. 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 Honda part.
