HEMI COIL HARNESS, LATE TYCO
SKU: H00E 558-311
Moderate — 2–4 hours
Description
Part #: 558-311
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.
Features:
- 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
