UF648 Ignition Coil & 97390 Spark Plug Kit for Chrysler, Dodge, Jeep, Ram & Volkswagen

This BDFHYK ignition service kit uses the UF648 ignition coil reference with the 97390 iridium spark plug reference for listed Chrysler, Dodge, Jeep, Ram, and Volkswagen applications. Rough running, hesitation, hard starting, or a misfire may involve ignition components, but other electrical, fuel, air, compression, timing, and mechanical conditions can produce similar symptoms.

UF648 / 97390 Application Check

Applications include select Chrysler 300 and Town & Country; Dodge Avenger, Challenger, Charger, Durango, Grand Caravan, and Journey; Jeep Cherokee, Grand Cherokee, Wrangler, and Wrangler JK; Ram 1500, 1500 Classic, C/V, ProMaster 1500, ProMaster 2500, and ProMaster 3500; and Volkswagen Routan.

Installation Checks

Compare the replacement coil body, connector, mounting points, and boot profile with the removed component.
Inspect connectors, wiring, and spark plug wells.
Use exact vehicle service specifications for plug gap and tightening torque.

Post-Installation Diagnosis

If a misfire remains after service, continue diagnosis of wiring, injectors, fuel delivery, intake leaks, compression, timing, and other engine conditions.

Difficulty Moderate

Estimated Time 0.5–1 hour

Tools Required

Screwdrivers
Service manual specific to your vehicle
Socket set and ratchet
Wrenches

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 vehicle brands are listed for this UF648 and 97390 kit? A: The product lists select Chrysler, Dodge, Jeep, Ram, and Volkswagen applications.

Q: Can I order by vehicle brand alone? A: No. Confirm the exact year, model, engine, connector, and original part references because one brand can use multiple ignition configurations.

Q: Which references should I compare? A: Compare UF648 for the ignition coil and 97390 for the spark plug, plus the original component references.

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 compare the plug reference for the exact engine.

Q: Should all ignition coils be replaced together? A: Not automatically. Replacement quantity should follow diagnosis, component 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 because gap and torque are not universal.

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

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

Before vs After Replacement

Replacing worn ignition coils and spark plugs helps restore stable ignition and smoother engine performance.

BEFORE

Rough Idle & Engine Vibration Noticeable engine shaking while idling. Irregular exhaust flow may indicate unstable ignition performance.

AFTER

Fast Start & Stable Idle IMore consistent spark delivery reduces misfires and stabilizes idle speed.

BEFORE

Sluggish Acceleration Weak throttle response at lower RPM. Vehicle may feel underpowered.

AFTER

Enhanced Power Response Improved throttle response and smoother acceleration

BEFORE

Increased Fuel Consumption Poor combustion can lead to higher fuel usage.

AFTER

Improved Fuel Efficiency Optimized ignition supports more efficient combustion.

Performance improvements may vary depending on vehicle condition.
