X4XZ Ignition Coil & Double Iridium Spark Plug Kit for 3.6L Pentastar V6 — 6-Pack UF807/93175, Improved Durability & Smooth Idle

The X4XZ UF807 ignition coil and 93175 double iridium spark plug kit is a six-cylinder replacement set designed to restore reliable spark, smoother idling, and consistent combustion for 3.6L Pentastar engines.

This complete kit includes six UF807 ignition coils and six 93175 double iridium spark plugs engineered to meet or exceed original equipment fit and performance. Built for a range of 2016–2021 Chrysler, Dodge, Jeep and Ram vehicles that use the 3.6L Pentastar V6, the components focus on longevity, noise suppression and steady high-voltage transfer to the plugs. The set replaces common OE part numbers so you can swap the entire bank at once and avoid piecemeal troubleshooting.

What improvements will I notice after installing this coil and spark plug set?

Replacing worn coils and spark plugs typically yields quicker starts, fewer misfires and smoother throttle response. The double iridium plugs retain sharp electrodes longer, while the coils use thermal-resistant materials and internal ferrite suppression to deliver clean, consistent spark energy.

• Reduced engine misfire and rough idle incidents
• More consistent ignition timing under load
• Improved cold-start combustion and drivability
• Extended service interval thanks to iridium electrodes

Which vehicles and OE numbers are compatible with this kit?

This kit is intended for 3.6L Pentastar V6 applications across multiple model years and brands. It lists several original-equipment references so you can confirm fitment against factory part numbers before purchasing.

• Common fits: 2017–2021 Chrysler Pacifica, 2016–2021 Dodge Durango, 2016–2021 Jeep Grand Cherokee
• Also for 2018–2021 Jeep Wrangler, 2020–2021 Voyager, 2019–2021 Ram 1500
• OE / replace numbers include 68223569AB/AD/AC and UF807 family numbers
• Package contains 6 ignition coil packs and 6 double iridium spark plugs

How durable and reliable are the UF807 coils and 93175 iridium plugs?

The 93175 plugs use double iridium tips which resist electrode wear far longer than conventional designs, offering a long service life and steady spark performance. UF807 coils incorporate stainless springs and ferrite noise suppression, plus thermoplastic connectors that resist heat-related cracking, contributing to consistent voltage delivery.

• Double iridium plugs designed for up to long operating life
• Stainless-steel internal spring for stable plug-to-coil contact
• Ferrite noise suppressor reduces radio-frequency interference
• Thermoplastic coil connectors resist thermal cycling damage

What should I expect during installation and aftercare?

Installation is straightforward for anyone familiar with coil-on-plug replacement—no separate instructions are included but the components match OE geometry for direct fit. After installation, allow a short break-in period; monitor for any diagnostic codes and torque spark plugs to factory specs to ensure proper seating and sealing.

• Direct-fit replacement — plugs and coils match OE design
• Torque spark plugs to manufacturer specification during install
• Check for absence of misfire codes after installation
• Contact after-sales support for any fitment or quality questions

Who is this for: This kit suits DIY enthusiasts and professional technicians replacing the entire ignition bank on Chrysler, Dodge, Jeep and Ram models equipped with the 3.6L Pentastar engine. It’s ideal if you want a full, like-for-like coil and plug replacement to eliminate intermittent misfires, improve throttle response, and avoid repeated service visits by updating to longer-lasting iridium plugs and robust coils.
