About this item

Product details

Gen III HEMI Coil Harness, Early Coils, for HP EFI & Dominator EFI;

Chrysler has used two different coils on the HEMI engine series with 2006 being the year that the change was phased throughout the truck and car line. Fortunately the two coils are very different visually and makes for a simple review. If the coil requires spark plug wires, it is the early coil. If the coil does not require plug wires and simply has two boots that connect to the plugs in the cylinder head, it is the later coil. View the image gallery for images of both types.;

Take control of your Gen III HEMI with Holley EFI by controlling fuel and spark. Great for power upgrades and engine swaps.
Capable of tuning with power adders such as nitrous, superchargers or turbos and compatible with methanol and water injection
Harnesses are available to connect to a Gen III HEMI engine for the most advanced fuel and timing controls available
Each Harness is designed in fit and function specifically for the Gen III HEMI engine platform
All wiring is TXL grade copper wiring with minimal weight, high temp sleeve in a small diameter
Factory style terminations provide a strong, secure connection
Connectors are OEM grade for a correct, positive fit
Each harness is routed through a split-loom braid for protection and great looks
