In this review of the Ignition Coil Pack UF502 paired with Iridium Spark Plugs 7781, the bottom line is simple: this kit is aimed at owners of late 2000s Chrysler and Dodge V6 models who need a cost-effective way to restore ignition performance. It delivers clear benefits for cars showing symptoms of aging ignition systems, such as rough idle, slow acceleration, or misfire codes, because the coils use quality silicon steel and imported materials while the spark plugs use iridium electrodes for improved starting and throttle response.

Key Features

  • Vehicle compatibility: Fits a range of Chrysler and Dodge 3.5L and 4.0L V6 models from the late 2000s, so buyers can match parts to specific model years before purchase.
  • Ignition coil construction: Coils are made with silicon steel, Japan-imported rubber, and varnished wire for durability and longer service life compared with basic replacements.
  • Spark plug material: Iridium electrodes and specialized ceramic are used to improve ignitability and throttle response for a more reliable start and acceleration.
  • OE cross-reference: Coils list several OE numbers such as UF502 and related codes, helping ensure correct fit when cross-checked with the vehicle.
  • After-sales support: The manufacturer provides lifetime after sales service, giving buyers an avenue for follow-up if fitment or performance questions arise.

Who It's For

This kit is best for owners of Chrysler 300, Sebring, Town & Country and compatible Dodge models from approximately 2006 to 2010 with the 3.5L or 4.0L V6 who are experiencing ignition-related symptoms or who are performing preventive maintenance after high mileage. It is particularly useful for DIY mechanics comfortable verifying OE numbers and replacing coil packs and spark plugs.

Those who should look elsewhere include owners of vehicles outside the listed model years or engines, and buyers who want brand-new OE dealer parts or factory warranties; this aftermarket kit requires careful OE checking before installation.

Pros & Cons

Pros

  • Good value for money with a combined coil pack and iridium plug set that improves engine responsiveness for many users.

  • Clear OE cross-reference information makes fitment checks straightforward when matched to the vehicle.

Cons
