UF648 Ignition Coil Pack and 97390 Spark Plug Set of 6 - Reliable V6

In this review the UF648 ignition coil pack and 97390 spark plug set is evaluated for owners of Chrysler, Dodge, Jeep and Ram vehicles with 3.2L and 3.6L V6 engines. The bottom line: this kit is for DIY mechanics and independent shops that need a straightforward, OE-form-fit replacement to restore ignition performance. The most convincing reason to buy is the matched coil and plug pairing designed to address misfires, rough idle, and poor fuel economy by delivering stable high voltage and improved ignition reliability.

Key Features

• Multivehicle compatibility: Supports a wide range of Chrysler, Dodge, Jeep, Ram and Volkswagen Routan models from about 2011 to 2020, making it useful for shops working on many V6 vehicles.
• Coil construction: Coils use silicon steel, high-pressure rubber sleeves and Japan-imported epoxy for durability and resistance to cracking or shorting under heat and vibration.
• High-quality winding: Germany-imported venameled wire in the coil improves long-term electrical stability and consistent high-voltage output across engine speeds.
• Iridium spark plugs: 97390 plugs feature extremely fine iridium electrodes and CNC-machined metal parts for reliable sparks, faster starts and reduced wear.
• Tested assembly: Each coil and plug is subject to quality control testing to reduce common ignition faults such as misfiring, stalling or check engine light triggers.
• Complete kit: The package includes six coils, six spark plugs and a manual so the full V6 ignition bank can be serviced at once.

Who It's For

This kit is best for owners and professional technicians working on 3.2L or 3.6L V6 Chrysler, Dodge, Jeep or Ram models who want a direct-replacement ignition solution that matches OE form and function. It is particularly suitable when multiple cylinders are showing ignition-related faults and a full-bank replacement is the efficient fix.

Owners of vehicles outside the listed model years, those with heavily modified engines, or anyone requiring brand-original factory parts for warranty reasons should consider other options. Also check fit carefully if previous feedback about loose O-rings is a concern for a particular engine variant.

Pros & Cons

Pros

• Good compatibility across many 3.2L and 3.6L V6 models, simplifying parts sourcing for multi-vehicle garages.
• Durable coil materials and quality wire winding aim to deliver long service life and stable voltage.
• Iridium spark plugs provide improved ignition performance and help faster starts and smoother acceleration.
• Valued as cost-effective and generally easy to install according to customer feedback.

Cons

• Some users reported mixed fitment details, such as loose O-rings on a minority of units, so inspect seals during install.
• Not branded as factory original parts, so buyers seeking OEM-branded components may prefer dealer-sourced units.
