Performance Ignition Coils for Chrysler 300 (2006-2020) 5.7L 6.1L 6.4L V8

High-Output Performance Ignition Coils for 2006-2020 Chrysler 300 (Gen III Hemi / LX/LD)

Upgrades factory ignition components to deliver a consistent, high-voltage spark, eliminating misfires and supporting optimal combustion in Gen III Hemi engines.

The Stock 300 Ignition System Limitations

Factory ignition coils degrade over time under the intense thermal cycling of the Gen III Hemi engine bays. The 5.7L, 6.1L, and 6.4L powerplants generate substantial radiant heat, which degrades the OEM coil housing epoxy and internal copper windings. This leads to increased electrical resistance, voltage leaks, and a noticeably weaker spark. Under high-load conditions or when utilizing aftermarket bolt-ons, this thermal degradation causes high-RPM misfires, sluggish throttle response, and incomplete fuel burn. The resulting drop in ignition efficiency directly robs the engine of horsepower, torque, and smooth idle stability.

The Engineering Solution

These replacement performance ignition coils are engineered with advanced thermal-resistant epoxies and upgraded primary and secondary copper windings to maximize voltage output. By increasing the magnetic field strength within the coil pack, they deliver higher spark energy than standard OEM equivalents, ensuring complete combustion. The reinforced silicone boots provide superior dielectric insulation, preventing arcing to the cylinder head block while enduring extreme operating temperatures. This robust internal construction ensures rapid spark recovery, supporting the higher cylinder pressures of the 300C, SRT8, and 392 models for restored power delivery, sharper throttle response, and reliable ignition timing across the entire RPM band.
