UF502 Ignition Coil Pack & 7781 Spark Plugs Set of 6 - Reliable

In this review the UF502 ignition coil pack and 7781 spark plug kit is examined for drivers who need a full ignition service for V6 Chrysler and Dodge platforms. The bottom line: this set is aimed at owners of compatible Dodge, Chrysler and Volkswagen vehicles who want a complete, value-oriented replacement that focuses on durable coil construction and high-performance iridium plugs. It stands out for delivering stable high-voltage output and quicker starts while providing an affordable way to address misfires, rough idle, or check engine light issues.

Key Features

• Multivehicle compatibility: The kit fits a wide range of Dodge, Chrysler and select Volkswagen V6 models, making it easy to replace all cylinders at once.
• Durable coil construction: Coils use silicon steel, Japan-imported epoxy and Germany venameled wire for longer service life and resistance to cracking and shorting.
• High-performance spark plugs: Iridium electrodes and isostatic ceramic insulators provide reliable ignition, faster starts and reduced spark plug wear.
• OE-equivalent fit and function: Coil and plug OE numbers are matched to common replacements so the parts meet factory form, fit and function expectations.
• Complete kit: You get six coil packs, six spark plugs and a manual in one package to service the entire engine bank in one job.
• Quality testing: Each component is tested to ensure stable high-voltage output and consistent performance across engine speeds.

Who It's For

This kit is best for owners of 2006-2011 V6 Dodge and Chrysler models (examples include Avenger, Charger, Challenger, Journey, Town & Country, Sebring, Pacifica and 300) and for those who prefer to replace the entire ignition set at once rather than installing single parts. It is also suitable for a Volkswagen Routan owner who requires the same OE references.

DIY mechanics and independent shops who value replacement parts that match OE reference numbers and emphasize durability will appreciate this kit. Those who require exact factory-branded components for dealer-level warranty matching or who need a model not listed should look elsewhere or confirm fit from the vehicle picture or detail page before ordering.
