ENA Ignition Coils Pack of 8 for 5.7L V8 HEMI - Direct-Fit Black, OEM-Fit UF504 Replacement

ENA ignition coils pack of 8 is a direct-fit replacement set engineered to restore reliable spark to 5.7L V8 HEMI engines in compatible Dodge, Chrysler, Jeep and Ram models.

If your V8 is misfiring, running rough, or showing a Check Engine light related to ignition, fresh coil packs are one of the simplest service items to bring performance and drivability back. This ENA kit supplies eight black coil packs matched to the factory electrical specifications and mounting pattern for many 5.7L HEMI-equipped vehicles from model years around 2006–2019. The set replaces common OEM part numbers (including UF504, 5C1569 and others), arrives with a 12-month warranty, and is designed for bolt-on installation with the same three-terminal connector arrangement as the factory units.

How does this coil pack set improve engine performance?

Worn or failing coils deliver weak or inconsistent sparks, causing misfires, loss of low-end torque, and reduced fuel efficiency. Installing a matched set of new coils restores consistent spark energy across all eight cylinders so combustion is balanced and smooth.

• Restores even firing across all cylinders to reduce misfires and rough idle.
• Improves throttle response and steady cruise performance.
• Helps maintain original fuel economy by ensuring complete combustion.
• Direct electrical compatibility eliminates adaptation or wiring changes.

Will these coils fit my vehicle and how easy is installation?

The pack is made to be a direct replacement for many Chrysler, Dodge, Jeep and Ram V8 models with 5.7L (and select 6.1/6.4/6.2) engines—check reference years and engine codes carefully. The coil packs use the factory bolt-on mounting and the same three-terminal connector, so installation is straightforward for most DIYers or a quick job for a mechanic.

• Replaces OEM numbers such as UF504, 5C1569, and IC584 for a correct fit.
• Bolt-on mount type with female connector and male terminals—no splicing.
• Compatible model families include Charger, Challenger, Ram, Durango, 300, Grand Cherokee, Commander, and Aspen (see full compatibility list).
• Pack of 8 covers all cylinders for complete replacement at once.

What are the technical specs and build details?

Each coil in the ENA set is built to operate at the vehicle’s 12V electrical system and uses the factory mating connector and terminal genders. The set is finished in a durable black housing designed to resist engine-bay heat and vibration for many miles of service.

• Voltage: 12V standard automotive ignition coil rating.
• Mount Type: Bolt-on for factory-style installation.
• Connector: female housing with three terminals; terminals are male where they meet the plug.
• Included: eight black coil packs and a 12-month warranty.

How long will these coils last and what about warranty?

Longevity depends on vehicle conditions and heat cycles, but replacing all eight at once reduces the risk of adjacent coil failures and uneven performance. ENA backs the coil pack set with a 12-month warranty to cover manufacturing defects under normal use.

• 12-month limited warranty included for peace of mind.
• Replacing all coils at once prevents mismatched performance across cylinders.
• Durable black housings resist heat and contaminants in the engine bay.
• Follow recommended torque and connector care during installation for best life.

Who is this for: This ENA pack of eight coils is aimed at owners and technicians working on Dodge, Chrysler, Jeep or Ram vehicles equipped with 5.7L HEMI (and certain 6.1/6.2/6.4 models) who want a reliable, direct-fit replacement set. It’s a practical purchase for anyone addressing misfires, rough idle, reduced fuel economy, or preventive maintenance to keep a V8 running smoothly without factory-level expense.
