BDFHYK Ignition Coil and 97390 Spark Plug Kit for Honda and Acura V6

Rough idle, hard starting, hesitation under load, or a cylinder-specific misfire may involve worn ignition components, but wiring, connectors, fuel delivery, intake leaks, sensors, compression, timing, and other mechanical conditions can produce similar symptoms. This BDFHYK ignition coil and spark plug kit pairs OE-style aftermarket ignition service components with 97390 iridium spark plugs for the Honda and Acura V6 applications listed below. Confirm the exact engine, connector shape, spark plug reference, and required service quantity before ordering.

Honda and Acura V6 Fitment

2008–2012 Honda Accord 3.5L V6
2011–2017 Honda Odyssey 3.5L V6
2009–2014 Honda Ridgeline 3.5L V6
2009–2015 Honda Pilot 3.5L V6
2009–2012 Acura RL 3.7L V6
2009–2013 Acura TL 3.5L V6

Fitment should be confirmed against the exact engine and the removed ignition components before installation. Conflicting or unverified application data is not used here.

97390 / LKR7BGPS Iridium Spark Plug Reference

The spark plug reference is 97390 / LKR7BGPS and describes an iridium electrode design. Confirm the spark plug reference required for the exact vehicle before installation.

How to Confirm Ignition Coil and Spark Plug Fitment

Confirm year, make, model, and engine.
Compare the removed ignition coil body, connector shape, keying, and boot profile.
Confirm the original OE or interchange reference on the removed component.
Confirm the service quantity required for the exact engine.
Verify the 97390 / LKR7BGPS spark plug reference for the exact application.

Ignition Coil Diagnostic Checks Before Replacement

A misfire code alone does not prove that an ignition coil has failed. Inspect wiring, connectors, spark plug wells, fuel delivery, intake leaks, sensors, compression, timing, and other mechanical conditions as part of the diagnosis.

Installation Checks for This Ignition Service Kit

Inspect wiring and electrical connectors before installation.
Check spark plug wells for oil or moisture.
Compare the old and new coil body, connector, and boot profile.
Use the exact vehicle service specification for spark plug gap and tightening torque.
Verify connector seating after installation.

These are BDFHYK OE-style aftermarket service components, not factory-branded parts.

Pre-Installation Checklist

Stop the engine before disassembling or replacing the ignition coil.
Check the spark plugs and spark plug wires as part of diagnosis.
Keep the installation area clean and dry.
Make sure the ignition coil connections are correct.
Refer to the service manual for your specific vehicle because removal order and connector or fastener details can vary by make and model.
Disconnect the negative battery cable before working on the ignition system.

Installation Steps

Disconnect the battery. Remove the negative battery cable by loosening the clamp bolt with a socket or wrench.
Locate the ignition coils on top of the engine. They may be attached to the engine block or surrounding components.
Disconnect and remove the old ignition coil. Remove the mounting bolts or screws and disconnect the electrical connector(s). The order can vary by vehicle, so follow the vehicle-specific service manual. Remove the old coil once fully disconnected.
If one coil serves multiple spark plugs and has multiple electrical connections, mark or label the connectors so they can be reattached to the correct terminals.
Install the new ignition coil in the reverse order of removal. Secure the mounting bolts or screws and reconnect the electrical connector(s) in the correct positions.
Reconnect the negative battery terminal. Hand-tighten the connection, then tighten the terminal bolt with a socket or wrench. Do not over-tighten.
Close the hood, start the engine with the vehicle in Park, and confirm it starts and idles normally. If it does, test-drive the vehicle.

Post-Installation Verification

Confirm the new ignition coil is securely mounted.
Confirm all electrical connectors are connected to the correct terminals.
Confirm the negative battery terminal is reconnected and tightened sufficiently without over-tightening.
Start the engine in Park and confirm it starts and idles normally.
If idle is normal, test-drive the vehicle and check for remaining misfire or drivability symptoms.

Troubleshooting

Spark plug and wire checks from the manual:
With the engine running, disconnect spark plug wires one at a time and observe engine-speed or roughness changes; the manual states that no significant change can indicate a bad spark plug.
The manual describes checking for spark by holding the end of a disconnected spark plug wire near a metal surface and looking or listening for a spark or cracking sound.
While the engine is cranked, check for spark at each spark plug wire; the manual states that no spark can indicate a dead wire.
Make sure battery, ignition, coil, and spark-plug wire connections are secure. Wiggle connections and retest if a loose connection is suspected.
Keep spark plug ends clean and free of dirt, oil, or grease; clean and retest before replacing a plug.
Inspect wires for cracked, cut, scraped, or burned insulation. Check boots and terminals for damage, corrosion, or poor contact.
Check for corrosion between the boot, spark plug, and ignition coil, and inspect the spark plug for discoloration or damage.
Inspect spring clips and wire retention at the distributor and spark plug ends to make sure connections are held securely.
Ignition coil failure can cause one or more cylinders to misfire, stuttering, sluggishness, and other drivability issues.

Q: How should I confirm the ignition coil before ordering?

A: Compare the original OE or interchange reference, coil body, connector shape and keying, and boot profile with the removed component before ordering.

Q: Does a misfire code prove the ignition coil is bad?

A: No. Wiring, connectors, fuel delivery, intake leaks, sensors, compression, timing, and other mechanical conditions can create similar symptoms.

Q: Should all ignition coils and spark plugs be replaced together?

A: Replacement should follow the vehicle condition, diagnostic results, service history, and the exact engine's service requirements. Confirm the required service quantity before ordering.

Q: What should I compare before installation?

A: Compare the removed and replacement coil body, connector shape and keying, boot profile, and spark plug reference, and inspect wiring and connectors.

Q: What spark plug gap should be used?

A: Use the exact vehicle service specification for the specific engine and spark plug application rather than a generic gap value.

Q: What tightening torque should be used?

A: Use the exact vehicle service specification for the specific engine and spark plug application.

Q: What should I inspect during installation?

A: Inspect wiring and electrical connectors, check spark plug wells for oil or moisture, and verify connector seating after installation.
