UF648 C1791 Ignition Coil Pack & Spark Plug Kit - Restores OEM Spark

Our review of the UF648 C1791 Ignition Coil Pack & Spark Plug Kit finds it best suited for owners of Chrysler, Dodge, Jeep, RAM and VW Routan vehicles with the 3.6L V6 who need a straightforward, direct-fit replacement. The kit's single biggest selling point is that it combines six OE-style ignition coils with six pre-gapped double iridium spark plugs in one package, which makes it a practical choice for anyone replacing all cylinders at once to restore ignition strength and reduce intermittent misfire.

Key Features

• Direct-fit connectors: OE-style connectors provide a plug-and-play installation that saves time and avoids adapter hassles.
• Complete six-cylinder kit: Includes six ignition coils and six double iridium spark plugs so the whole ignition bank can be serviced in one job for consistent performance.
• Engine compatibility: Designed for a wide range of 3.6L V6 applications across Chrysler, Dodge, Jeep, RAM and VW Routan models, reducing the risk of ordering the wrong part.
• Heat-resistant construction: Coil bodies are built to endure under high under-hood temperatures for longer service life in harsh conditions.
• Pre-gapped plugs: Spark plugs arrive pre-gapped and ready to install, helping ensure correct ignition timing and consistent spark delivery from the start.

Who It's For

This kit is aimed at DIY mechanics and independent shops looking to replace a full bank of ignition coils and spark plugs on 3.6L V6 engines from about model year 2011 through 2020 across the listed Chrysler, Dodge and Jeep fitments. It is especially useful when misfires or rough idle indicate multiple cylinder ignition issues or when preventive maintenance is desired.

Buyers who need a single-coil repair or who require OEM-brand parts for a warranty-sensitive repair may prefer to source individual factory coils or dealership parts. Also, owners of excluded variant engines or years not listed should verify fitment before purchase.

Pros & Cons

Pros

• Complete six-coil and six-plug kit simplifies service and ensures matched components.
• Easy installation thanks to OE-style connectors and pre-gapped plugs reduces labor time.
• Improves throttle response and combustion stability when original coils or plugs are worn.

Cons

• Quality feedback is mixed from some customers, so results may vary compared with factory OE units.
