Holley LS Coil Harnesses

Holley LS coil harnesses are factory replacements for stock LS coils. These EFI LS coil sub harnesses are intended to be used with factory LS coils and various Holley EFI main harnesses with coil-on-plug connectors. They are built with the same high-quality connectors and wire loom found on all Holley EFI harnesses, guaranteeing a perfect match in your engine bay. Are you tired of scouring the junkyard for stock LS coil sub harnesses? Holley has the solution.

Holley LS coil harnesses feature:

* OEM connectors provide a secure connection between your ECU and Ignition Coils
* Techflex F6 braided wire loom keeps your engine bay looking clean, while providing abrasion resistance
* Plug-and-play fitment
* Can be used to replace a damaged factory coil harness
