What Does the APDTY 140104 Ignition Coil Do?
The ignition coil transforms your vehicle's 12-volt battery power into the thousands of volts needed to create a spark at the spark plug. In modern coil-on-plug ignition systems—like those found in Nissan and Infiniti V6 engines—each cylinder has its own dedicated coil mounted directly over the spark plug.
The APDTY 140104 is engineered to meet OE specifications for coil-on-plug applications on 3.5L and 4.0L V6 engines. It delivers consistent spark energy across the RPM range, ensuring complete combustion, smooth idle, and optimal power output. When a coil fails, that cylinder stops firing, leading to drivability issues and potential catalytic converter damage from unburned fuel.
What Are the Symptoms of a Failed Ignition Coil?
Ignition coil failure is common in high-mileage Nissan and Infiniti V6 engines. Symptoms include:
- Check engine light: Diagnostic trouble codes P0300 (random misfire), P0301-P0306 (cylinder-specific misfire), or P0351-P0356 (ignition coil circuit fault)
- Rough idle or engine stumble: The engine shakes or hesitates, especially at idle or under load
- Loss of power: Reduced acceleration, sluggish response, or hesitation when merging or climbing hills
- Poor fuel economy: Incomplete combustion wastes fuel and can damage the catalytic converter
- Engine stalling: In severe cases, multiple coil failures can cause the engine to stall
- Visible arcing or burning smell: Cracked coil boots or internal coil breakdown may produce visible sparks or a burning odor
If you experience any of these symptoms, scan for diagnostic codes and inspect all ignition coils and spark plugs. Replacing only the failed coil is often sufficient, but worn spark plugs or damaged plug boots can cause premature coil failure.

How Do You Install the APDTY 140104 Ignition Coil?
Replacing an ignition coil on a Nissan or Infiniti V6 is a straightforward task for DIYers with basic hand tools. General installation steps include:
- Disconnect the battery: Remove the negative battery cable to prevent electrical shock or accidental shorting.
- Access the coils: Remove the engine cover (if equipped) and any intake components blocking access to the coil pack.
- Disconnect the electrical connector: Press the release tab and pull the connector straight off the coil.
- Remove the mounting bolt: Most coils are secured by a single 10mm bolt. Remove the bolt and set it aside.
- Extract the old coil: Pull the coil straight up and out of the valve cover. Twist gently if it resists, but do not force it.
- Inspect the spark plug and boot: Check the spark plug for wear, fouling, or damage. Replace if necessary. Inspect the rubber boot for cracks or carbon tracking.
- Install the new coil: Insert the APDTY 140104 into the spark plug well, pressing firmly to seat the boot on the spark plug terminal.
- Secure the coil: Reinstall the mounting bolt and torque to factory specification (typically 62-80 in-lbs; consult your service manual).
- Reconnect the electrical connector: Push the connector onto the coil until it clicks.
- Reassemble and test: Reinstall any removed components, reconnect the battery, and start the engine. Clear diagnostic codes and verify smooth operation.
Safety note: Never work on the ignition system with the engine running or the key in the "on" position. High-voltage arcing can cause injury. Wear insulated gloves and safety glasses. If you are not comfortable performing this repair, consult a qualified technician.
Frequently asked questions
How many ignition coils does my V6 Nissan or Infiniti have?
All 6-cylinder engines covered by the APDTY 140104 use a coil-on-plug design with six individual coils—one per cylinder. If one coil fails, you can replace just that coil, but inspecting all six (and the spark plugs) is recommended.
Can a bad ignition coil damage my catalytic converter?
Yes. A misfiring cylinder sends unburned fuel into the exhaust, where it can ignite inside the catalytic converter, causing overheating and permanent damage. Replace failed coils promptly to avoid costly converter replacement.
Should I replace all six coils at once?
It's not required, but many technicians recommend replacing coils in sets (especially on high-mileage engines) to prevent repeat failures. If your vehicle has over 100,000 miles and one coil has failed, others may be near the end of their service life.
Will the APDTY 140104 fit my 4-cylinder Nissan?
No. The APDTY 140104 is designed exclusively for 6-cylinder (V6) Nissan and Infiniti engines with 3.5L or 4.0L displacement. Four-cylinder models require a different coil design. Always check the compatibility chart for your specific engine configuration.
The APDTY 140104 ignition coil delivers OE-quality performance for Nissan and Infiniti V6 engines, restoring smooth idle, full power, and reliable starting. Whether you're diagnosing a misfire code or performing preventive maintenance on a high-mileage vehicle, this direct-fit coil provides a cost-effective solution backed by proven compatibility with 3.5L and 4.0L DOHC V6 applications.
