Performance Ignition Coils for Dodge Ram (2012-2020) 5.7L 6.4L V8

High-Output Performance Ignition Coils for 2012-2020 Dodge, Ram 1500, 2500, Ram, Ram 1500, Ram 2500 (HEMI V8 / DS, DT, DJ)

Replaces degrading factory ignition coils to deliver a stronger, more consistent spark for improved combustion, idle stability, and throttle response under heavy engine loads.

The Stock 1500, 2500, Ram, Ram 1500, Ram 2500 Ignition Shortcomings

OEM ignition coils on high-mileage 5.7L and 6.4L HEMI engines are notorious for thermal degradation and voltage leaks. Mounted directly to the valve covers, these factory coils are subjected to extreme under-hood temperatures and continuous thermal cycling. Over time, the standard epoxy resins break down, leading to micro-cracks in the plastic coil housing. This inevitably causes internal arcing, spark blowout under heavy load, and misfires that trigger a check engine light (CEL). Furthermore, the factory primary and secondary winding ratios struggle to maintain consistent high-voltage output during the sustained engine loads required for towing, resulting in a sluggish throttle pedal and decreased fuel efficiency.

The Engineering Solution

These performance ignition coils are engineered specifically to eliminate spark blowout and resist the high-heat environment of the HEMI cylinder heads. Upgraded with a high-temperature epoxy compound, thermal-resistant polymer housings, and reinforced copper windings, they ensure maximum voltage transfer directly to the spark plugs without risk of internal grounding. The optimized winding configuration yields a substantially higher energy output compared to standard OEM units, promoting a faster, more complete fuel burn in the combustion chamber. This translates to smoother idling, crisper throttle response, and reliable spark delivery during high-rpm pulls or heavy-towing scenarios. Featuring a direct plug-and-play design, these units lock securely onto the factory harness without splicing.
