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

The Holley Spark Plug Wire Set Universal GM LS Cut to Fit is an essential ignition upgrade for LS engine builders, hot rod enthusiasts, and engine swap specialists who require dependable spark delivery in tight engine compartments. This universal cut-to-fit design is ideal for custom header configurations and unique intake manifolds, allowing for a clean installation where standard wires may not fit properly.

Engineered with 8mm silicone insulation and low-resistance cores, these wires effectively suppress EMI while ensuring consistent ignition voltage to all eight cylinders. The cut-to-fit feature enables precise measurement and trimming of each wire to the exact length needed, eliminating excess slack and preventing compression against hot headers.

This wire set is particularly beneficial for LS swap applications and custom installations, where one-size-fits-all harnesses can lead to routing conflicts. The black jacket not only resists UV degradation but also maintains flexibility in high-temperature environments, extending the life of your ignition system during high-performance use.
