Making the switch to smart coils on your gen III Hemi on Holley EFI? Our application-specific kit makes a hassle-free transition from the factory Chrysler 2-pin coils.
Smart coils are an excellent choice for ignition on high compression / high boost race cars, but have very specific power and grounding requirements to hit their full spark potential. Our complete harness kit allows for just that with a simple plug-and-play installation. Our smart coil wiring kit is also one of the cleanest, best-finished and most inclusive kits available.
Compatible with (including and not limited to) the following Holley EFI main engine harnesses:
- 558-115
 - 558-116
 
Features
- Compatible with IGN-1A smart coils from all popular brands, including Holley, Haltech, FuelTech, AMP EFI, FireCore and more.
