Spark Plug Wire Set Univ GM LS Cut to Fit - Black

The Holley Spark Plug Wire Set Universal GM LS Cut to Fit delivers dependable ignition performance for GM LS-platform V8 engines with field-proven spiral-core construction. This black wire set is engineered for straight and 90-degree plug boot configurations, allowing technicians and engine builders to customize routing around tight engine bay layouts without compromising spark delivery or EMI suppression.

Built with 8.2mm spiral-core wire, this universal LS ignition set resists heat degradation and maintains consistent electrical conductivity across extended operating ranges. The cut-to-fit design eliminates wasted length, reducing capacitive losses and allowing precise installation in high-performance applications where every electrical factor matters. Socket-style connections ensure secure engagement with factory-style distributor caps and coil packs. The black jacket provides clean engine bay aesthetics while protecting the core from UV exposure and oil contamination—critical factors in street, race, and restomod builds where long-term reliability is non-negotiable.

LS enthusiasts—whether tuning carbureted stroker engines, converting late-model trucks to classic chassis, or optimizing crate engine installations—rely on quality ignition components to eliminate misfire variables. This Holley wire set addresses the common challenge of routing around modern engine management, turbo plumbing, and tight accessory packaging. Cut-to-fit construction proves especially valuable in fabrication scenarios where OEM wire harnesses don't accommodate custom header angles, remote battery boxes, or non-standard ignition module placement.
