KacuYelin UF807 Ignition Coil Pack & Iridium Spark Plug Kit, Set of 6 — 3.6L V6 Fit, OEM-Style Performance

Complete ignition replacement kit: six KacuYelin UF807 ignition coil packs paired with six iridium spark plugs engineered to restore reliable spark and smoother starts for compatible 3.6L Jeep, Dodge, RAM and Chrysler engines.

This kit combines long-life iridium spark plugs and precision-matched coil packs to deliver consistent ignition performance for many 2016–2021 3.6L V6 vehicles. KacuYelin designed the components to meet OEM form, fit and function while using upgraded materials—high-purity copper windings and high-temperature ceramics—to improve spark stability and resist wear. The set is sold as a plug-and-play replacement for the listed OE numbers, simplifying service intervals and helping address misfires, rough idle or reduced fuel efficiency caused by worn ignition parts.

Which vehicles will this UF807 coil and plug kit fit?

The KacuYelin UF807 set is targeted at 3.6L V6 models across Jeep, Dodge, RAM and Chrysler lines from 2016 through 2021. Always verify compatibility by entering your vehicle year, make, model and engine into the fitment checker before ordering.

• Jeep: Gladiator (2020–2021), Grand Cherokee (2016–2021), Wrangler (2018–2021)
• Dodge: Durango (2016–2021)
• RAM: 1500 (2019–2021)
• Chrysler: Pacifica (2017–2021), Voyager (2020–2021)

How do these coil packs and iridium plugs improve performance?

Improvements come from materials and manufacturing focused on consistent high-voltage delivery and durable electrode geometry. The coils use German-imported copper windings and a silicon steel core to sustain stable output, while the iridium plugs use 360° laser-welded electrodes for concentrated spark energy.

• More stable high-voltage output reduces misfires and ignition dropouts
• Iridium electrode resists wear—long service life up to 60,000–100,000 miles
• Improved combustion can support better throttle response and cleaner burn

What are the build quality and standards behind this kit?

KacuYelin manufactures these parts in TS16949-compliant facilities, combining quality-grade materials with production controls to meet OEM tolerance and reliability standards. Components are designed for plug-and-play installation to match the listed OE numbers and simplify technician or DIY replacement.

• Coil construction: high-temperature epoxy, anti-oxidation finishes, precision windings
• Spark plugs: high-alumina ceramic insulation and nickel-rich structure for corrosion resistance
• Manufacturing: TS16949-certified production and R&D testing protocols

How should I install and maintain this ignition kit?

Installation follows standard ignition service steps: remove old coils and plugs, check and clean the well, set correct torque on new plugs, and reconnect coils securely. Routine inspection every 30,000–60,000 miles helps spot wiring or connector issues that can affect ignition performance.

• Use OEM torque specs for spark plug installation and anti-seize if recommended
• Inspect coil pack connectors and wiring harness for corrosion or damage
• Replace the entire set at once to maintain uniform performance across cylinders

Who this is for: installers, DIY mechanics and fleet owners running 3.6L Pentastar-equipped Jeep, Dodge, RAM or Chrysler vehicles who want a full ignition refresh with components designed to match OEM dimensions while providing upgraded durability. If you need dependable, long-life plugs and coil packs to address misfires, poor starts or to preempt ignition wear, this KacuYelin UF807 set is a direct replacement option—just confirm fitment with your vehicle details before purchase.
