KacuYelin UF648 Ignition Coil Pack & Iridium Spark Plug Kit — 6‑Pack for 3.2L/3.6L V6 (2011–2020), OE‑Fit Durable

This complete set contains six UF648 ignition coil packs and six iridium-tipped spark plugs designed as OE-style replacements for V6 applications from 2011–2020. Built from high-conductivity copper windings, corrosion-resistant alloy steel, and high-density alumina ceramic, the components are manufactured under TS16949 processes and tested for stable voltage delivery and thermal performance. The kit lists multiple OE numbers to match factory parts and includes fitment across Charger, Challenger, Wrangler, Cherokee, 300, Town & Country, Ram 1500 and other compatible models—check vehicle compatibility before purchase.

Which vehicles and engines does this UF648 kit fit?

These ignition coil packs and iridium spark plugs are intended for 3.2L and 3.6L V6 engines installed in a range of model years from 2011 to 2020. Compatibility covers many Dodge, Chrysler, Jeep, Ram and Volkswagen Routan variants; confirm exact fit with your VIN or the seller’s compatibility tool to avoid mismatches.

• Fits: Dodge Charger/Challenger (2011–2020), Grand Caravan, Avenger, Durango, Journey
• Fits: Chrysler 200/300, Town & Country (2011–2017 range)
• Fits: Jeep Wrangler (2012–2018), Cherokee, Grand Cherokee (2011–2020 ranges)
• Fits: Ram 1500 and C/V models, Volkswagen Routan (selected years)

How are the coil packs and spark plugs built for durability?

The coil packs use imported German copper windings and alloy steel components for high conductivity and oxidation resistance, reducing the risk of voltage drop. The iridium plugs employ a 360° laser-welded center electrode and high-alumina ceramic to maintain thermal stability and resist wear over time.

• Coil materials: copper wire and corrosion-resistant alloy steel
• Spark plug electrode: continuous laser weld with high iridium content
• Ceramic insulator: 95% high-alumina for stable heat transfer
• Manufacturing: TS16949-certified production and factory testing

Will installing this kit affect fuel economy or drivability?

Replacing worn coils and spark plugs can restore consistent spark energy and combustion, which often improves throttle response and steady engine idle. While results vary by vehicle condition, the manufacturer cites potential fuel-efficiency recovery when worn ignition parts are replaced, and many users notice smoother starting and fewer misfires.

• Targets misfire, rough idle, weak acceleration and hard starts
• Designed to meet OE electrical output and thermal specs
• Helps return spark timing consistency to factory levels

What installation and verification steps should I follow?

Installation typically replaces one-to-one with the original coil packs and spark plugs; basic hand tools and an appropriate torque wrench are recommended. Always reference the vehicle service manual for torque specs, gapping notes, and replacement intervals, and clear fault codes or run a diagnostic after installation to confirm resolved ignition issues.

• Verify fit using VIN or the seller’s compatibility navigation tool
• Replace coils and plugs in matched sets for consistent performance
• Follow factory torque specs and anti-seize recommendations
• Run diagnostics after install to confirm no active misfire codes

Who is this for: This KacuYelin UF648 coil pack and iridium spark plug kit is aimed at DIY mechanics, professional technicians and vehicle owners who need a full six-cylinder ignition replacement for select 3.2L/3.6L V6 Chrysler-family engines. If your vehicle shows intermittent misfires, decreased fuel efficiency, starting difficulty or uneven idle and it matches the listed models, this kit offers OE-style materials and manufacturing to restore reliable spark performance. Always confirm model-year compatibility with your vehicle identification number or compatibility tool before ordering.
