Ignition Coil Pack Set UF504 Compatible with Chrysler Dodge Jeep

In this review of the SYKRSS ignition coil pack set UF504, the bottom line is simple: this kit is for owners of compatible Chrysler, Dodge and Jeep V8 vehicles who need an affordable, plug-and-play replacement to restore ignition performance. The reviewer found the set of eight coils delivers quicker ignition response and straightforward installation for many 5.7L, 6.1L and 6.4L engines, while offering durable construction meant to resist heat and corrosion. This is a practical aftermarket choice when OE coils show wear, misfire, or trigger the check engine light.

Key Features

• Multivehicle compatibility: The set covers a wide range of Chrysler, Dodge and Jeep V8 applications so a single kit can service many model years.
• OE replacement fit: Designed to replace part numbers such as UF504 and C1526 so buyers can confirm fit by matching OEM numbers.
• Durable materials: Built from heat- and abrasion-resistant materials to maintain stable high-voltage output under engine heat.
• Improved ignition: Intended to reduce misfires, hard starting and rough idling by restoring spark strength to the plugs.
• Easy installation: Most coils are plug-and-play, which helps DIYers and shops swap all eight without special tools.
• Value package: The kit includes eight coils and a manual, backed by a 24-month support promise from the brand.

Who It's For

This coil pack set is aimed at owners and independent mechanics working on Chrysler Aspen, Chrysler 300, Dodge Magnum, Durango, Challenger, Charger, Ram and Jeep Grand Cherokee or Wrangler models listed in the compatibility notes who are experiencing ignition-related symptoms or who prefer replacing all coils at once. It suits people who want a cost-effective repair with generally plug-and-play installation rather than an OEM-priced option.

It is less appropriate for vehicles outside the listed engine families or for owners who require factory-branded components for warranty or resale reasons. Buyers should confirm compatibility by checking the vehicle year, engine displacement and the original equipment part number before purchase.

Pros & Cons

Pros

• Good overall quality and durable materials that resist heat and corrosion.
• Clear value for money when replacing multiple coils at once.
• Easy to install for most users with basic tools and mechanical experience.

Cons

• Functionality feedback is mixed: some users still reported misfires, so results may vary by vehicle condition.
• Fit is not universally agreed upon by all customers, so confirm OE numbers before ordering.
