Product Details

The Holley EFI 561-113 is a complete spark plug wire set designed specifically for LS engines, offering the flexibility of custom-cut installation. Each wire measures 36 inches long and comes unterminated, allowing you to route and cut them to the exact length needed for your specific engine configuration.

Key Features:

  • 8mm diameter high-performance spark plug wires
  • 36-inch unterminated wires for custom routing and length adjustment
  • Low 350 Ohms per foot resistance for excellent spark energy transfer
  • High noise suppression to prevent EMI interference with electronic systems
  • Locking dual crimp style terminals ensure secure, positive engagement
  • Choice of spark plug boot angles: 135° or 180° configurations available
  • Available in multiple colors: Red, Black, or Grey to match your engine bay

These professional-grade plug wires deliver reliable ignition performance while maintaining clean electrical signals. The cut-to-fit design eliminates excess wire routing and provides a clean, custom appearance under the hood. Perfect for LS swap applications, custom engine builds, or replacement on modified engines where standard pre-cut lengths won't work.
