The Holley EFI 558-326 LS Coil Extension Harnesses provide a professional plug-and-play solution for extending ignition coil connections on LS engine swaps and custom builds. Each set includes four 36-inch extension harnesses with OEM-style connectors that ensure secure, reliable connections between your ECU and LS ignition coils.

Key Features:

• 36-inch length provides flexibility for custom engine bay layouts and tight installations
• OEM-quality connectors ensure proper fitment and reliable electrical connections
• Techflex F6 braided wire loom protection offers abrasion resistance and a clean, professional appearance
