Set of 8 Ignition Coil Pack UF270 and Iridium Spark Plugs 4503

In this review of the set of 8 ignition coil pack UF270 and iridium spark plugs 4503, the bottom line is simple: it is aimed at owners of Chrysler, Dodge and Jeep vehicles with the 4.7L V8 (and some 3.7L V6) who need a direct-replacement ignition service kit that restores misfires and rough idle without fuss. The reviewer found the kit delivers dependable ignition performance, meets OE form and function claims, and includes everything needed for a full ignition tune-up in one purchase, making it a practical option for DIY mechanics and professional installers who want straightforward replacement parts.

Key Features

• Multivehicle Compatibility: Covers many Chrysler, Jeep, Dodge and Mitsubishi models with the 4.7L V8 and select 3.7L V6 applications, reducing the need to hunt for separate parts.
• OE Replacement Fit: The coil packs are designed to match common OE numbers such as UF270 and SKIC038 so they can be swapped in without modification for a direct fit.
• Iridium Spark Plugs: The included 4503 iridium plugs are specified to meet OE standards, offering improved durability and consistent spark delivery over standard copper plugs.
• Durability Under Heat: Materials are rated for high temperature resistance to help maintain performance under engine heat and reduce premature failure.
• Complete Kit: The package includes eight coils, eight spark plugs and a manual, providing everything needed for a full-bank replacement in one shipment.

Who It's For

This kit is best for owners of Dodge Dakota, Durango, Ram 1500 and Jeep Grand Cherokee or Commander models from the model years listed in the compatibility notes who want a single purchase to replace all ignition coils and plugs at once. It suits DIYers who are comfortable swapping coils and plugs and professionals who need a ready-to-install set for common 4.7L V8 service jobs.

It is not ideal for vehicles that are outside the stated compatibility list or for customers who require OEM-branded parts with original factory packaging; buyers should verify OE part numbers against their vehicle before ordering to ensure exact fit.

Pros & Cons

Pros

• Good value for a full eight-coil and eight-plug replacement compared with buying parts individually.
• Most users report improved engine smoothness, fewer misfires and restored power after installation.
• Easy to install as a direct-replacement, saving time during a full-bank service.

Cons

• Fitment can be mixed; some customers reported loose O-rings on a few coils so verify fit and seal before final installation.
