Performance Ignition Coils for Jeep Grand Cherokee (2012-2019) 5.7L 6.2L 6.4L V8

High-Output Performance Ignition Coils for 2012-2019 Jeep Grand Cherokee (Hemi V8 / WK2)

Upgrades the factory ignition system to deliver a stronger, more consistent spark, resolving misfires and optimizing combustion for Hemi-powered WK2 Grand Cherokees.

The Stock Hemi Ignition Shortcomings

Factory OEM ignition coils on the 5.7L, 6.2L, and 6.4L Hemi engines are notorious for thermal degradation over extended mileage. Subjected to extreme under-hood temperatures—especially in the confined engine bays of SRT and Trackhawk models—the epoxy potting and internal windings break down over time. This thermal stress leads to voltage leaks, weak spark discharge, cylinder misfires under heavy load, and a sluggish throttle response. Furthermore, high-compression and forced-induction applications exacerbate these weaknesses, often triggering dreaded P0300 series check engine light codes.

The Engineering Solution

These performance ignition coils are engineered with upgraded primary and secondary copper windings to increase voltage output and spark energy. Utilizing high-dielectric epoxy and thermal-resistant silicone boots, the coils provide superior insulation against arching and heat soak. This improved thermal management ensures consistent energy transfer to the spark plugs, resulting in a cleaner fuel burn, restored horsepower, and smoothed-out idle. The direct plug-and-play design utilizes factory mounting points and OEM-style connectors, requiring no splicing or ECU tuning to eliminate misfires and support higher-cylinder pressures.
