KacuYelin Ignition Coil Pack & Iridium Spark Plugs Set of 8 — Direct-Fit 4.7L V8 Replacement, OE-Equivalent

The KacuYelin UF270 ignition coil pack paired with a set of eight iridium spark plugs is a complete plug-and-play replacement designed to restore reliable ignition and consistent spark for 4.7L V8 Chrysler-family engines.

If your Dodge, Jeep or Ram with a 4.7L V8 is experiencing misfires, rough idle, or diminished throttle response, worn coils and plugs are common causes. This kit combines OE-equivalent coil packs (replacement UF270 / 5C1114 / 56028138) and precision iridium plugs engineered for high-temperature durability and focused sparks. The parts are built in TS16949-capable facilities using high-purity copper windings, silicon steel cores and 95% alumina ceramic insulators to match OEM fit and function.

How will these coils and iridium plugs affect starting and idle?

New ignition coils and fresh iridium plugs often restore consistent spark delivery, improving cold starts and smoothing idle. Because the coil and plug set is matched for the 4.7L V8, it reduces irregular firing that leads to stalling or rough idling.

• Direct-fit replacement for OEM UF270 / 5C1114 / 56028138 numbers
• High-temperature epoxy and corrosion-resistant materials for stable high-voltage output
• Iridium center electrode and precision welding for concentrated sparks
• Plug-and-play installation—no modification required

Will fuel economy or emissions improve after installation?

Replacing degraded coils and plugs can help the engine burn fuel more efficiently by restoring optimized combustion. While outcomes vary with vehicle condition and driving habits, properly functioning ignition components often contribute to reduced unburned fuel and lower exhaust emissions compared to worn parts.

• Iridium plugs resist wear and resist electrical loss over long service life
• More precise ignition timing supports steadier combustion
• May reduce carbon buildup thanks to cleaner, more complete burns
• Designed to meet emissions expectations for compatible vehicles
