UF486 Ignition Coil & XP104 Spark Plug Kit for 3.0L V6 Applications

This BDFHYK ignition service kit pairs the UF486 ignition coil reference with the XP104 spark plug reference for listed Ford Fusion, Lincoln Zephyr, Mercury Milan, and Mazda Tribute 3.0L V6 applications. A cylinder-specific misfire can involve a coil or spark plug, but diagnosis should also consider wiring, fuel delivery, intake leaks, compression, timing, and other engine conditions.

UF486 / XP104 Vehicle Applications

2006–2009 Ford Fusion
2006 Lincoln Zephyr
2006–2009 Mercury Milan
2006–2009 Mazda Tribute

Confirm the exact engine and compare the original coil and spark plug references before ordering.

UF486 Ignition Coil References

References include UF486, DG514, C1594, IGC0158, 5C1651, 6E5Z12029BA, 6E5E12A375BB, and ZZD4-18-100.

Spark Plug References

XP104 is the primary spark plug reference in the product title. Additional interchange references include SP433, AGSF32WM, and AGSF-32W-MX.

Installation Checks

Inspect coil connectors and wiring.
Check spark plug wells for oil or moisture.
Compare coil body, connector shape, and boot profile with the removed part.
Use vehicle-specific service information for spark plug gap and tightening torque.

If a Misfire Continues

Continue diagnosis instead of replacing additional ignition parts without confirmation. Fuel, air, electrical, compression, timing, and mechanical conditions can also cause a misfire.

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.

BDFHYK Ignition Coil Installation Guide

Q: Which vehicles are listed for this UF486 kit? A: The product lists 2006-2009 Ford Fusion, 2006 Lincoln Zephyr, 2006-2009 Mercury Milan, and 2006-2009 Mazda Tribute applications.

Q: Which spark plug reference is primary? A: XP104 is the primary spark plug reference in the product title. SP433, AGSF32WM, and AGSF-32W-MX also appear as interchange references.

Q: Should I confirm the engine before ordering? A: Yes. Confirm the exact 3.0L V6 application and compare the original ignition parts before ordering.

Q: Does a misfire code prove the ignition coil is bad? A: No. Wiring, spark plugs, injectors, fuel delivery, intake leaks, compression, timing, and other conditions can cause similar symptoms.

Q: Should the spark plugs be checked during coil service? A: Yes. Inspect plug condition and service history and compare the plug reference for the exact engine.

Q: Should all ignition coils be replaced together? A: Not automatically. Replacement quantity should follow diagnosis, condition, service history, labor access, and exact engine requirements.

Q: What should be compared before installation? A: Compare coil body, connector keying, mounting points, boot profile, and spark plug reference with the removed parts.

Q: What if there is oil or moisture in a spark plug well? A: Correct the contamination source and clean the plug well before judging the replacement coil.

Q: What spark plug gap and torque should be used? A: Use the exact vehicle service specification. Gap and torque are not universal.

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

Q: Are these factory-branded OEM parts? A: No. These are BDFHYK OE-style aftermarket service components.
