The Holley HP EFI Sub-Harnesses - Smart Coil (SKU HLY558-312) is a precision ignition coil wiring harness specifically designed for Holley HP and Dominator EFI fuel injection systems. This sub-harness integrates smart coil technology, ensuring reliable spark delivery across various engine configurations and displacement classes.
The smart coil technology employed in this harness allows individual coil packs to fire each spark plug independently, reducing electrical noise and enabling precise timing control throughout the RPM range. The harness is engineered for compact routing within modern engine bays, with termination connectors and wire gauge optimized to handle the current demands of multi-coil ignition systems.
This harness is particularly beneficial for builders looking to enhance ignition performance in high-boost forced induction or naturally aspirated applications. While it is compatible with Holley HP and Dominator EFI systems, users should verify fitment for their specific applications to ensure optimal performance.
