Holley | HEMI Coil Harness

Holley – HEMI Coil Harness

Description

The Holley HEMI Coil Harness (p/n 558-311) is designed for Gen III HEMI engines equipped with late coils (no spark plug wires required). This harness enables advanced fuel and timing control through Holley EFI systems. Built with high-temperature TXL copper wiring, small diameter sleeving, and protected by a split-loom braid. OEM-grade connectors ensure a precise, secure fit, and the harness is compatible with power adders such as nitrous, superchargers, and turbos.

Note: Chrysler used two different coil types on HEMI engines. Late coils are identified by their direct connection to spark plugs in the cylinder head, without plug wires.
