UF648 Ignition Coil Packs & Iridium Spark Plugs Set of 6 - Reliable

In this review of the UF648 Ignition Coil Packs & Iridium Spark Plugs set, the bottom line is straightforward: this kit is for owners of Chrysler, Dodge, Jeep, RAM and compatible vehicles with 3.2L or 3.6L V6 engines who need an affordable complete ignition replacement. The reviewer found the set useful as a matched six-pack solution that replaces OE parts UF648 and 97390, simplifying repairs for multi-coil V6 engines. The primary reason to buy is practical value: a full set of ignition coils and spark plugs designed to fit the listed years and models, backed by a two year unlimited mileage warranty.

Key Features

• Complete set: Includes 6 ignition coils and 6 iridium spark plugs so all cylinders are serviced at once for consistent performance.
• Direct fit: Sold as OE part replacements UF648 and 97390 to match fitment for many 2011-2020 Chrysler, Dodge, Jeep and RAM models.
• Durable materials: Coils use silicon steel with Japan-imported rubber and Germany-imported varnished wire for longevity under engine heat and vibration.
• Wide vehicle coverage: Compatible with numerous 3.2L and 3.6L V6 applications including Cherokee, Wrangler, Charger, Challenger, Grand Cherokee and ProMaster vans.
• Warranty support: The product includes a two year unlimited mileage warranty which provides reassurance after installation.

Who It's For

This kit is ideal for DIY mechanics or independent shops tackling a full ignition service on V6 vehicles specified in the fitment list, especially when multiple misfires or aging coils suggest replacing all six units together. It suits owners who prefer replacing coils and plugs as a matched set to avoid uneven wear and to restore consistent idle and throttle response.

Drivers with different engine sizes, older model years outside the stated fitment, or those requiring OEM-branded parts for dealer records should look elsewhere. Also, anyone uncertain about compatibility should verify vehicle application before purchasing to avoid fitment issues.
