UF640 Ignition Coil and 4504 Spark Plug Set for Dodge, Ram, and Jeep 3.7L V6

This BDFHYK UF640 ignition coil and 4504 iridium spark plug set is designed for listed Dodge, Ram, and Jeep 3.7L V6 applications. It is intended for ignition service when the original coils or spark plugs have been diagnosed as worn, weak, damaged, or related to misfire symptoms. Buyers commonly check exact 3.7L fitment, OE reference numbers, plug quantity, connector style, and whether the kit matches their cylinder count and service plan before ordering.

Vehicle Fitment for This UF640 Ignition Kit

Make	Model	Listed Years	Engine	Fitment Check

Fitment note: Do not order by model name alone. Dodge, Ram, and Jeep applications can vary by year, engine, trim, and ignition layout. Confirm the 3.7L V6 engine and original part references before installation.

When Ignition Coils and Spark Plugs May Need Service

Ignition coils and spark plugs may need inspection when the engine has hard starting, rough idle, hesitation, misfire symptoms, poor acceleration, poor fuel economy, or a check engine light. If a coil circuit code is present, wiring, connectors, and control signals should be checked before assuming the coil is the only failed part. Review the P0351-P0354 codes guide when circuit-related codes appear.

UF640 and 4504 Reference Checks

Compare UF640, GN10457, 5149199AA, 68320417AA, C754, 49022, SKIC511, 9212133, IGC0177, and COP553 with the original coil.
Compare spark plug reference 4504 with the required plug specification for the 3.7L V6 application.
Confirm that 3 ignition coils and 6 iridium spark plugs match the service quantity for the listed engine.
Check connector orientation, coil body shape, mounting points, plug reach, seat type, and gap requirement.

Service Notes for Dodge, Ram, and Jeep Ignition Coils and Spark Plugs

Before installation, inspect the old plugs for fouling, check plug gap requirements, review connector locks, and follow vehicle-specific torque guidance. If a misfire remains after installing ignition coils and spark plugs, continue diagnosis by checking wiring, injector operation, intake leaks, fuel pressure, and compression. For a broader repair overview, see how ignition coils and spark plugs work together in the ignition coil vs spark plug guide. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded Dodge, Ram, or Jeep part.
