BDFHYK Ignition Coil Pack and Iridium Spark Plug Kit for 3.6L V6 — Set of 6 UF648/97390, Improved Starting & Throttle Response

BDFHYK’s kit pairs six UF648 ignition coil packs with matching 97390 iridium spark plugs to restore reliable ignition for many 3.6L Jeep, Dodge, Chrysler and Ram engines.

This complete ignition pack replaces worn coils and plugs on compatible 3.6L V6 applications, improving starting consistency and throttle response without aftermarket tuning. The coils use durable silicon steel cores and imported components while the spark plugs feature an iridium electrode and high-grade ceramic insulator. Before purchase, confirm OE reference numbers and vehicle compatibility to ensure a correct fit.

Which vehicles and engine codes does this kit fit?

This set is built for 3.6L V6 gasoline engines across multiple FCA platforms.

• Check OE references: UF648, UF-648, 0221504032, C1791, 5C1848, 05149168AI, 2505484816.
• Confirm spark plug OE: 97390.
• Verify year, engine and VIN compatibility before ordering.

How do the ignition coils and iridium plugs improve performance?

Replacing aged coils and plugs restores consistent spark timing and combustion efficiency, which helps reduce misfires, rough idle and sluggish throttle response. The coils are wound with varnished wire and use quality rubber components to resist heat and vibration, while iridium plugs maintain a stable, long-lasting spark gap.

• Stronger, cleaner spark reduces misfires and hesitation.
• Iridium electrode resists wear for longer service intervals.
• High-quality materials improve thermal and vibration durability.

What symptoms indicate I should replace both coils and plugs?

Common warning signs include rough or vibrating idle, difficulty starting, decreased acceleration, and increased fuel consumption. If your vehicle has exceeded about 80,000 km or shows these symptoms, replacing the coil-pack-and-plug set together prevents repeated labor and ensures matched components.

• Intermittent misfire codes or engine light illumination.
• Poor cold starts or slow rev-up after acceleration.
• Noticeable drop in fuel economy or engine smoothness.

What should I check before ordering and installing this set?

Always confirm OE numbers and match them to your vehicle’s parts list to avoid fitment issues. Use the images and the vehicle compatibility information to verify fit, and consider replacing all six coils and plugs at once for balanced performance across the V6.

• Match OE part numbers and VIN-based fitment details.
• Inspect wiring harness and connectors for damage before install.
• Torque spark plugs to manufacturer specs and follow anti-seize recommendations.

Who this is for: Mechanics, DIY owners, and fleet managers driving compatible 3.6L Jeep, Dodge, Chrysler or Ram models who want a matched, full-set replacement of ignition coils and iridium spark plugs. Choose this BDFHYK kit when you need a complete six-cylinder ignition refresh using higher-grade coil materials and iridium electrodes for longer-lasting, reliable spark performance.
