GDUKOP UF640 Ignition Coil and Spark Plug Kit for 3.7L V6 — 3 Coils, 3 Wires, 6 Iridium Plugs

GDUKOP UF640 kit replaces three ignition coils, three plug wires and six iridium spark plugs to restore reliable ignition for 3.7L V6 Dodge, Jeep and Ram engines.

This comprehensive ignition service kit combines upgraded coils, high-conductivity plug wires and long-life iridium plugs to address misfires, rough idle and weak throttle response on compatible 3.7L V6 vehicles. The components are matched to factory-style fitment numbers and designed to simplify replacements on models such as Dakota, Nitro, Durango, Commander, Grand Cherokee, Liberty and Ram 1500 from the model years listed. Below you’ll find targeted answers to common buyer questions, plus clear specifications to help confirm fit and performance expectations.

What exactly is included in the GDUKOP UF640 ignition kit?

This package bundles three direct-fit ignition coils, three replacement spark plug wires and six iridium spark plugs. Each part uses cross-reference numbers to match OEM fitment for straightforward installation.

• 3x ignition coils (part references: 68320417AA, 5149199AA, UF640, C1652, 5C1709, GN10457, IC743SB, IC743, E1140)
• 6x iridium spark plugs (part references: 68303923AA, 4504)
• 3x spark plug wires (part references: 5149211AE, 27738, 671-6290)

How will these upgraded components affect engine behavior?

Replacing worn ignition parts with these upgraded items typically reduces misfires and smooths idle, while helping restore throttle response and easier cold starts. The coils’ improved conductor design and iridium’s superior spark characteristics work together to promote more complete combustion without changing engine tuning.

• Stronger, more consistent spark from iridium plugs supports reliable firing
• Copper-core coils increase ignition response and combustion stability
• Silicone-insulated wires minimize interference and maintain conductivity

Which vehicles are compatible, and how do I confirm fitment?

This kit is built for Chrysler-family 3.7L V6 applications—check model and year to ensure compatibility before ordering. Use the included part numbers and compare them to your current parts or vehicle service manual to confirm a match.

• Common fits include: Dodge Dakota/Nitro (2009–2011), Durango (2009), Commander/Grand Cherokee (2009–2010), Liberty/Ram 1500 (2009–2012)
• Verify by comparing OEM reference numbers printed on existing coils, plugs and wires
• Refer to product images and part lists for visual confirmation prior to purchase

What materials and construction features improve durability and performance?

The kit uses copper-core coils and silicone-insulated wires for dependable conductivity and heat resistance, while iridium spark plugs offer higher wear resistance than standard electrodes. These material choices aim to extend service life and maintain consistent ignition under regular driving conditions.

• Copper core coils for quicker electrical transfer and improved combustion efficiency
• Silicone insulation on wires to resist cracking and electrical leakage
• Iridium spark plugs for longer intervals between replacements and stable spark energy

Who this is for: The GDUKOP UF640 kit is intended for owners, mechanics and DIY enthusiasts who need a matched set of ignition coils, wires and plugs for 3.7L V6 Dodge, Jeep and Ram models. It’s suitable when diagnosing persistent misfires, restoring engine smoothness, or performing routine ignition maintenance with parts that mirror OEM form, fit and cross-reference numbers.
